The DS18B20 digital temperature sensor provides 9-bit to 12-bit celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-wire bus that by definition requires only one data line(and...
The sensor device will receive the command when it checks in with the MQTT server and the firmware on the command will be interpreted and executed. In both cases the MQTT protocol is used as a bridge between the appliance (arduino) and control unit (raspberry pi). Using a broker in the ...
