💬 Gesture controlled MySensors, Floor lamp

[AWI]

@TheoL A simple answer... The Ld33 should have more than enough reserve to power the pro-mini, sensor and drive the FET's. The estimated consumption should not exceed 30mA. With a voltage drop over the regulator of around 8 Volt the dissipation is 240mW. Even without cooling the regulator will should not get warm. Unless you are powering more (led's etc.) from the 3.3V line.

[TheoL]

@AWI I have connected everything as you said. So I'm powering the mosfet, the sensors, the radio and the ProMoni from the LD33V. When I didn't put in the 7808, the LD33V became really hot even with a heat sink. Which with my lack of electrnoic knowledge suggest that the LD is losing too much heat on power transformation.

After I added the 7808 both regulators get warm, but still can be touched.

So would a switching regulator be a better solution? If so I'll look for a circuit and order the parts tonight.

[Jens Grivolla]

The LM2575T-3.3 seems to fit and costs around 50 cents on AliExpress. According to the datasheet (http://www.mouser.com/ds/2/308/LM2575-D-88310.pdf) you can have input voltages up to 45V. Efficiency might not be the best, but definitely better than a linear regulator.

This is just what I came up with when looking for switching 3.3v regulators, I don't have any actual experience with it.

And as @AWI said, your circuit really should be using very little power. From your description, you are burning 500mA@12V = 6W which is absolutely huge. That's a lot of heat to dissipate. Normal consumption for an Arduino when active (without doing anything to lower it, such as using sleep states) is around 25mA@5V = 0.125W and likely quite a bit less for a 3.3V Pro Mini. Even counting some consumption for your sensors you are at around 50 to 100 times the normal consumption (which you all have to dissipate through your heat sinks).

[TheoL]

@Jens-Grivolla @AWI I'm going for the lazy road, since my time is a bit spare at the moment. Would this be a good switching regulator? It's a bit high priced, but for a first try I don't mind. I can always lookup schematics and build one for future projects.

Thanx in advance!

[AWI]

@TheoL I have a bunch of these laying around doing nothing... drop me your address in a PM (chat) and I will send you one (faster and cheaper).. still curious what is dissipating that much in your circuit..

[Jens Grivolla]

@TheoL I'm far from being an expert, so you may want to get someone else's opinion on it, but to me it looks good. Supports sufficiently high input voltages, good efficiency, and it seems to already have all the capacitors and everything, so you can get rid of all of that in your circuit.

Still, even if it was 500mA at 3V (1.5W) instead of 500mA at 12V (6W) (getting rid of all the voltage regulation losses), that would still be around 10 times what I would expect. So something strange is going on.

[TheoL]

@AWI I'll send you a DM in a minute. Thanx in advance. If I'm not mistaken, the gesture sensure is drawing a lot. And I also noticed a big spike while the node's is sending a message to the gateway.

[AWI]

@TheoL The APDS should take less than 1 mA according to the datasheet. The "spike" you get during send should also not be more than 30mA...

[mfalkvidd]

Got my gesture sensor from China today. Took a while to figure out that I had to solder the bridge for the ir led. Thanks a lot for the notes about setting gesture gain, I wasn't able to get gestures working until I found that note. The sensor works great now!

[Lars65]

Is it anybody who have converted it to mysensors 2.0?

[pjjarzembowski]

Hi, I'am new with this but I am going to build a kitchen lamp with this scetch. Unfortunately it doesn't work with Mysensors 2.0 library :( Befor I bought a devices for the lamp I was trying to remake the program for mysensors 2.0 I have to wait for my devices from aliexpress for almost two another months so I am going to post my correctet program and I would like to ask someone who has this lamp build with old library if he could test it. Thenk you very much in advance.

And this is the code. It compiles well in compiler program.

  Supported gesture:
  1. Left to right stroke: turns lamp on
  2. Right to left stroke: turns lamp off
  3. Down to up stroke: increases brightness (When brightness is already at max, the lamp will blink - duration and blink count can be changed in the sketch)
  4. Up to down stroke: decreases brgihtness (When brightness level is at 0 the lamp is off)
  
  The gesture sensor ues in this Sketch is an APDS-9960 RGB and Gesture Sensor, sold by SparkFun. They can be found on eBay and Aliexpress as well.
  See Sparkfuns hookup guide for pin lay-out ( https://learn.sparkfun.com/tutorials/apds-9960-rgb-and-gesture-sensor-hookup-guide )

@pjjarzembowski I'm sorry my dear friend. I've been really occupied the last month. Can't wait until it's getting less busy at work. Than I'll have some time to see if I can help you.
But I've read somewhere that the cheaper versions of the gesture sensors aren't that great. Curious about your findings.

@pjjarzembowski said in 💬 Gesture controlled MySensors, Floor lamp:
Hello!!
I can now say that the program below, is working in mysensors 2.0. It was tested in arduino Uno (china clone) and in arduino Nano (china clone). The gesture controller is also from China.
But additionaly I had to change the line:
void incomingMessage(const MyMessage &message) {
to
void receive(const MyMessage &message) {

and I had to change the file in arduino library:

In the file SparkFun_APDS9960.cpp, search and find the line:
if( !setLEDBoost(LED_BOOST_300) ) {
and edit it to read:
if( !setLEDBoost(LED_BOOST_100) ) {

That is all. It works fine :)
Thanks Theo for a Great program :)

[pjjarzembowski]

For those eager to built something more I am posting a new version, with included sensors for temperature and Himidity DHT22 (Pin D4), MQ135 (Pin AI 3), KY-026 IR Flame Sensor (Pin AI 1) it could also be a light sensor LM393, Led (Pin D3), I used LM2596 for 5V which I have taken from 12V power strip. 3.3 V I have taken from arduino UNO. I got some problems with arduino nano, when dealing with bigger powers for led like 50W so that is why I used arduino Uno, it works fine. The problems was that it freezes (I think it was because the quality of power for 3.3V). In the lower powers like 10W there was no problems for arduino nano.

Hello. Can somebody publish working code just for gesture and LED dimming with latest mySensors library? Thank you.

@APL2017 Posting one question multiple times isn't gonna give you an answer quickly. I just wanted to say that.

I see the code on the website is still in pre MS 2.0. It should be easy to convert it to MS 2.0. The only problem is that I don't have the hardware setup to check if it works. If I can find some time this week I will convert it, so that it at least compiles. But I can not test it and can't promise I will finish it this week.

But @pjjarzembowski version should work, you should only strip out the extra sensors he attached to his node.

After playing with dimmers and Domoticz for quite some time, I've discovered that 15 brightness levels is all I need. Because it's hard to see the difference is brightness level if you have 100 levels. And also it takes a lot of gestures to move from max to min. So the code can be simplified more. By just mapping the Domotics level (1-100) to (1-15) and the opposite when you send the nodes brightness level to Domoticz.

Also Domoticz behaves odd when it comes to dimmer actuators as I discovered during a project I'm working on now. There are some work arounds for that, which envolve storing the brightness levels on the eeprom of your node. I know 100000 times is a lot. But I really don't see the need to store each brightness level change in the eeprom.
