Humidity, temperature, motion and bunch of relays...
-
Hi everybody,
I'm trying to have a sketch for my leaving room which should have 8 relays, humidity, temperature and motion sensors.
I was able to merge few sketches to one and it works fine with 4 relays but i have problem with second "array" or sensors
this is my working sketch#include <MySensor.h> #include <SPI.h> #include <Wire.h> #include <DHT.h> #include <SimpleTimer.h> #define CHILD_ID_HUM 20 #define CHILD_ID_TEMP 21 #define CHILD_ID_MOTION 22 #define RELAY_1 14 // Arduino Digital I/O pin number for first relay (second on pin+1 etc) #define NUMBER_OF_RELAYS 4 // Total number of attached relays #define RELAY_ON 0 // GPIO value to write to turn on attached relay #define RELAY_OFF 1 // GPIO value to write to turn off attached relay #define HUMIDITY_SENSOR_DIGITAL_PIN 19 #define MOTION_SENSOR_DIGITAL_PIN 3 #define INTERRUPT MOTION_SENSOR_DIGITAL_PIN-2 // Usually the interrupt = pin -2 (on uno/nano anyway) unsigned long SLEEP_TIME = 600000; // Sleep time between reads (in milliseconds) - 10mins MySensor gw; DHT dht; SimpleTimer timer; float lastTemp; float lastHum; boolean lastTripped; boolean metric = true; MyMessage msgHum(CHILD_ID_HUM, V_HUM); MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP); MyMessage msg(CHILD_ID_MOTION, V_TRIPPED); void setup() { // Initialize library and add callback for incoming messages gw.begin(incomingMessage, AUTO, true); dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("HumTempRelayMotion", "1.4"); // Register all sensors to gw gw.present(CHILD_ID_HUM, S_HUM); gw.present(CHILD_ID_TEMP, S_TEMP); gw.present(CHILD_ID_MOTION, S_MOTION); // Fetch relay status for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) { // Register all sensors to gw (they will be created as child devices) gw.present(sensor, S_LIGHT); // Then set relay pins in output mode pinMode(pin, OUTPUT); // Set relay to last known state (using eeprom storage) digitalWrite(pin, gw.loadState(sensor)?RELAY_ON:RELAY_OFF); } //Serial.begin(9600); timer.setInterval(30000, getMeasure); metric = gw.getConfig().isMetric; } void loop() { // Alway process incoming messages whenever possible gw.process(); timer.run(); boolean tripped = digitalRead(MOTION_SENSOR_DIGITAL_PIN) == HIGH; if (tripped != lastTripped) { lastTripped = tripped; Serial.print("M: "); Serial.println(tripped); gw.send(msg.set(tripped?"1":"0")); // Send tripped value to gw } } void incomingMessage(const MyMessage &message) { // We only expect one type of message from controller. But we better check anyway. if (message.type==V_LIGHT) { // Change relay state digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF); // Store state in eeprom gw.saveState(message.sensor, message.getBool()); // Write some debug info Serial.print("Incoming change for sensor:"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } } void getMeasure() { delay(dht.getMinimumSamplingPeriod()); float temperature = dht.getTemperature(); if (isnan(temperature)) { Serial.println("Failed reading temperature from DHT"); } else if (temperature != lastTemp) { lastTemp = temperature; if (!metric) { temperature = dht.toFahrenheit(temperature); } gw.send(msgTemp.set(temperature, 1)); Serial.print("T: "); Serial.println(temperature); } float humidity = dht.getHumidity(); if (isnan(humidity)) { Serial.println("Failed reading humidity from DHT"); } else if (humidity != lastHum) { lastHum = humidity; gw.send(msgHum.set(humidity, 1)); Serial.print("H: "); Serial.println(humidity); } }

What is not working? The sensors (DHT & PIR) or the relays?
You have a function "void getMeasure' but you don't specifically call for it in your main loop.
What is the timer for?
-
Sorry I was to fast. I have problem with second "array" or sensors, first is working on pins 14-17 so analog. Second part should work on pins 5-8 but I have no idea how to make this. All works fine now but on 4 relays, I need to add 4 more.
-
@Tomasz-Pazio I read too fast as well, did not see 'timer.setInterval(30000, getMeasure);
You could use an Array to link the relay pins to Relay 1-8.
-
@Dwalt think that I undersand the idea but no idea how to write this in code, google gives a lot of examples but hard for me to code this
-
an approach with the relays would be like this bit of (untested) code:
#include <MySigningNone.h> #include <MyTransportNRF24.h> #include <MyTransportRFM69.h> #include <MyHwATMega328.h> #include <MySensor.h> #include <SPI.h> #define NUMBER_OF_RELAYS 8 #define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relay const int relayPin[NUMBER_OF_RELAYS] = {5,6,7,8,14,15,16,17}; //<<<<<<<pin numbers MyTransportNRF24 radio(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW); MyHwATMega328 hw; MySensor gw(radio, hw); void setup() { gw.begin(incomingMessage, AUTO, true); gw.sendSketchInfo("multiRelay", "1.0"); for (int i = 0; i < NUMBER_OF_RELAYS; i++) { gw.present(i, S_LIGHT); pinMode(relayPin[i], OUTPUT); digitalWrite(relayPin[i], LOW); } } void loop() { gw.process(); } void incomingMessage(const MyMessage &message) { if (message.type == V_LIGHT) { digitalWrite(relayPin[message.sensor], message.getBool()? RELAY_ON : RELAY_OFF); } }

@BulldogLowell works fine with this
thanks for support.

Hey !
I'm trying to use your code to do a Motion/temp/humidity sensor, but I dont know why the motion sensor is sending 0/1/0/1... if there is nothing moving ?!
Here is my code :
#include <SPI.h> #include <MySensor.h> #include <DHT.h> #include <SimpleTimer.h> #define CHILD_ID_HUM 0 #define CHILD_ID_TEMP 1 #define CHILD_ID_MOT 2 #define MOTION_SENSOR_DIGITAL_PIN 3 #define HUMIDITY_SENSOR_DIGITAL_PIN 4 //#define INTERRUPT MOTION_SENSOR_DIGITAL_PIN-2 unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds) MySensor gw; DHT dht; SimpleTimer timer; float lastTemp; float lastHum; boolean lastTripped; MyMessage msgHum(CHILD_ID_HUM, V_HUM); MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP); MyMessage msgMot(CHILD_ID_MOT, V_TRIPPED); void setup() { gw.begin(); dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN); // Send the Sketch Version Information to the Gateway gw.sendSketchInfo("Humidity/Motion", "1.0"); pinMode(MOTION_SENSOR_DIGITAL_PIN, INPUT); // Register all sensors to gw (they will be created as child devices) gw.present(CHILD_ID_HUM, S_HUM); gw.present(CHILD_ID_TEMP, S_TEMP); gw.present(CHILD_ID_MOT, S_MOTION); timer.setInterval(30000, getMeasure); } void loop() { timer.run(); boolean tripped = digitalRead(MOTION_SENSOR_DIGITAL_PIN) == HIGH; if (tripped != lastTripped) { lastTripped = tripped; Serial.print("M: "); Serial.println(tripped); gw.send(msgMot.set(tripped?"1":"0")); // Send tripped value to gw } } void getMeasure() { delay(dht.getMinimumSamplingPeriod()); float temperature = dht.getTemperature(); if (isnan(temperature)) { Serial.println("Failed reading temperature from DHT"); } else if (temperature != lastTemp) { lastTemp = temperature; gw.send(msgTemp.set(temperature, 1)); Serial.print("T: "); Serial.println(temperature); } float humidity = dht.getHumidity(); if (isnan(humidity)) { Serial.println("Failed reading humidity from DHT"); } else if (humidity != lastHum) { lastHum = humidity; gw.send(msgHum.set(humidity, 1)); Serial.print("H: "); Serial.println(humidity); } }Do you have any idea what could be causing that ?
Regards !

@petoulachi it looks like your input pin for the sensor is floating. You can enable the internal pull-up to check ( INPUT_PULLUP i.s.o. INPUT)
-
I'm sorry I'm a newbie with arduino so I don't understand what you want me to test ?
-
If you were meaning that I have to do
pinMode(MOTION_SENSOR_DIGITAL_PIN, INPUT_PULLUP);instead of
pinMode(MOTION_SENSOR_DIGITAL_PIN, INPUT);It changes nothing !
-
I found where was the problem, I'm really a newbee... The motion sensor was plugged to the 3.3VCC, not 5V, doing this strange behaviour !
