The DS18B20 digital thermometer 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 ground) for communication with a central microprocessor
In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply
Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus
Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area
Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems
The Shelly Temperature Probe needs to be purchased in conjunction with a Shelly 1 / 1PM and the Shelly Temperature Add-On which allows the connection between your relay and temperature probe.
