Feature: 1. HIGH ACCURACY CHIP: The sensor probe uses the 4X series chip and is built on the newly optimized for CMOSens chip, features low power consumption, high accuracy specifications and a maximum supply voltage range of 3.3V, which is ideal for mobile and battery driven applications. The integrated PTFE filter membrane provides additional particle protection with humidity accuracy of ±3%RH and temperature accuracy of ±0.2℃, enabling the sensor to operate in harsh conditions 2. STRONG PRACTICABILITY: Sensor probe is suitable for monitoring in computer room, HVAC, weather station, warehouse, site concrete test block detection, agricultural greenhouse, flowers, nursery and soil temperature and humidity measurement 3. STRONG FUNCTIONALITY: Sensor probe has complete calibration, digital output, IIC interface, I2C serial interface, easy to integrate, the relative humidity of air is a function of temperature 4. RELIABLE AND DURABLE: The temperature and humidity sensor probe adopts advanced batch processing technology and excellent hardware design, with high reliability, long term stability and long life 5. LIGHTWEIGHT AND COMPACT: The temperature and humidity sensor probe is small in size and light in weight, easy to carry and install, and does not take up too much space Specification: Item Type: Temperature Humidity Sensor ProbeOperating Current: 80%, may cause temporary signal drift(drift after 60 hours +3%RH). When the sensor is restored to normal working conditions, it will slowly recover to the correct state. Long time use under abnormal conditions will accelerate the aging of products.
