CO sensor gone mad

moskovskiy82 25 Dec 2016, 19:48 last edited by

Have around 5 nodes around the house and the latest one completed sends spikes from 50 to 800 ppm almost every minute. The only idea i have - it's happening because of the power supply (MQ-2 attached to the power supplies 5v and GND). Will adding a capacitor help out to smooth out the voltage? And what is the recommended capacity? Have tried already replacing the sensor

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Old topic, I know. Did anything ever come of this? I'm also thinking it would be easy & cheap to get the espnow working as a transport layer. I found this: https://www.mysensors.org/apidocs-beta/classESPNOW.html But it goes above my head and abilities when it comes to code.

Hi, I'm glad CodeGarage is taking over! Please are there any updates since January what's happening? The GitHub repo hasn't gotten commits for over a year. Thanks!

It seems you can access the child ID from the sent message by looking at the destination property. If you have the message object, you can extract the ID directly from there.

When connecting an accelerometer to your PC, consider its communication protocol (I2C or SPI) and the appropriate interface device, like a microcontroller (e.g., Arduino). You may also need additional hardware for voltage adjustment or signal conditioning, depending on the sensor’s specifications.
