Temperature & Humidity

About

Temperature sensing and thermal management components are essential for monitoring, controlling, and responding to heat in electronic systems, industrial equipment, and environmental monitoring applications. From temperature-triggered relay modules to high-performance Peltier thermoelectric coolers, our range covers both sensing and active thermal control for engineers and makers. Our Temperature & Humidity collection includes: Temperature-Sensitive Relay Modules — 5V NTC thermistor-triggered relay modules for automatic temperature-based switching; no microcontroller required — ideal for fan control, heater cutoff, incubator regulation, and thermal protection circuits with adjustable trigger threshold Peltier Thermoelectric Coolers — TEC1-12705 and TEC1-12706 thermoelectric modules for solid-state cooling and heating; rated at 12V with 5A and 6A maximum current respectively; used in CPU coolers, portable refrigerators, laser diode cooling, and precision temperature control systems Temperature & Humidity Sensors — DHT11 and DHT22 digital sensors for combined ambient temperature and relative humidity measurement; compatible with Arduino, Raspberry Pi, and ESP32 via single-wire digital interface All modules feature standard connector interfaces for easy integration into prototyping and production systems. Compatible with 3.3V and 5V microcontroller platforms.
