The XH-W1209 Temperature Controller Module is a high-precision digital thermostat designed to monitor and control temperature automatically. It features a clear LED display, onboard relay, and an NTC temperature sensor probe for accurate readings.

This module allows users to set upper and lower temperature limits. When the measured temperature crosses the set threshold, the relay automatically switches connected devices ON or OFF, enabling precise temperature control.

With its simple interface and adjustable parameters, the XH-W1209 is widely used in temperature control applications such as incubators, refrigerators, aquariums, heating systems, and industrial automation.
