The IP voltmeter v2.3 is a device for measuring 2 voltages and temperature over the internet. The board also contains a relay that can control various other devices.
The temperature is measured by an external temperature sensor, which operates in a wide range. The sensor is waterproof.
This board does not implement advanced functions (alert, cloud, remote DB) like some other boards.

Temperature sensor
As a sensor is used temperature sensor DS18B20. The thermometer uses a 1-pin bus, so only 3 pins are needed: Vdd, GND, DATA.
The colour coding of the cables is: GND is black, Vdd is red and DATA is yellow
The cable is 1 meter long. The sensor is waterproof. When connected to the input connector, the sensor immediately sends the measured temperature.
