The NTC Thermistor Temperature Sensor Module is a compact, low-cost solution designed to detect ambient temperature with high sensitivity. This module features an NTC thermistor for precise temperature sensing and uses an LM393 comparator to provide a clean, digital switch output. The module operates within a voltage range of 3.3V to 5V and has an adjustable temperature detection threshold, which can be set using the onboard potentiometer. It is ideal for various applications such as environmental temperature monitoring, water tank temperature control, and fan cooling systems. The module is easy to install, thanks to its fixed bolt hole design.
