HTH240 Temperature and Humidity Sensor is a high-protection with IP65 protection, rain and snow resistance and good ventilation. The circuit adopts imported industrial grade microprocessor chip and imported high-precision temperature sensor to ensure excellent reliability, high precision and interchangeability. This product uses a hard-mounted probe, and the unique waterproof treatment process completely solves the problem of short life of the probe condensation state. This probe will not be damaged even if it is placed in water for a long time. Analog and digital output supported.
