Hi everyone,
Ive posted same topic in sensor subforum and got no answers which made me think I didnt choose the right subforum.
Im using CJMCU-8118 3in1 (co2, voc and temperature) sensor for my project of measuring outdoor air parameters along with DHT11 sensor for temperature and humidity. Its connected to nodemcu v2.0 board and it sends data to the database on remote server. Everything works fine when nodemcu is working non-stop. My plan was to reduce battery discharge by reducing power consumption of the module and I introduce deep sleep mode. DHT11 keeps sending normal values but CJMCU sends only zeroes. CJMCU is using I2C communication so Im not sure if deep sleep influences that in any way.
In first try I was powering the sensors directly from the board which was powered by external power source, but then I thought maybe voltage pins of the board were influenced by deep sleep mode so I connected the sensors directly to the external power source so that they are under power all of the time, but still the problem persists.
Any ideas on why this is happening?
How are you waking the node board, using D0 ?
Are you waking the sensor board?
