W1209 Temperature Control Switch Module

The W1209 Temperature Control Switch Module is a compact and intelligent temperature controller designed for DIY electronics, automation, and cooling or heating applications. It allows you to set, monitor, and control temperature accurately using an onboard digital display and sensor probe.

This module uses an NTC thermistor sensor to measure temperature and a relay output to control external devices such as fans, heaters, or coolers. In addition, it features an easy-to-read 3-digit LED display and three control buttons for setting temperature thresholds and parameters.

Because it supports a wide operating voltage range (DC 12V) and precise temperature control (−50°C to +110°C), it’s suitable for incubators, thermostats, aquariums, and environmental monitoring systems. Also, it offers memory retention, so your settings are saved even after power loss.
