Re: Raspberry Pi with multiple wireless sensors

Hi, have you heard of espruino, they have a low power mode which only consumes 11mA - so your sensor can sleep in between temperature readings, espruinos also use ESP8266 for the WiFi connection. Charging and replacing those 20 batteries could become a full time job. However if your hives are too f...

Re: Raspberry Pi with multiple wireless sensors

Use ESP8266s rather than Arduinos. It's a billion times easier to get an ESP8266 connected to your WiFi. Run Mosquitto on your Raspberry. Get the sensors to publish MQTT messages with readings from your sensors. You can then subscribe to those MQTT topics in any way you like. This is running on my ...

Raspberry Pi with multiple wireless sensors

Experts, I am about to try making a remote temperature monitoring system. I have around 20 Bee hives and each hive needs two sensors to read the hive temperature - one at the bottom area and one at the top. New to the world of raspberry and sensors ! With my limited understanding, I plan to place a ...
