Description
USB relay board with four channels and connected TCN75A temperature sensor to it.. The relays can handle up to 7A(10A) at 220VAC/120VAC and the sensor can measure temperature from -40 C up to +100 C with accuracy +-0.5 C (typical) and +- 3 C (max). The software we provide makes this USB relay card ideal for applications like temperature monitoring (USB thermometer), temperature loging or simple USB thermoregulator.

The sensor
Please note the attached TCN75A sensor is not designed as a probe but it is PCB only with IDC connector. It is not sealed. It is strongly recommend to use it in dry environment. Do not use it for temperature measurements for water or other liquids!
