Product Summary: consists of an all--design ASIC dedicated chip, an improved MEMS capacitive humidity sensor and a standard on-chip temperature sensor. The performance and reliability have been greatly improved, surpassing the level of the previous . The sensor module has a more stable performance in harsh environment. At the same time, has higher cost-effectiveness and applicability, due to the improvement from miniaturization. Each sensor is strictly calibrated and tested to its high quality. Product Description: Is a kind of sensor of humidity and temperature with One-Wire Bus Protocol. It can be applied to HVAC, dehumidifier, testing and inspection equipment, consumer products, automobiles, automatic control, data loggers, weather stations, home appliances, humidity control and other application fields which need to detect and control temperature and humidity. Relative humidity and temperature output Superior sensor performance, typical accuracy RH: ±2%, T: ±0.3℃ Wide voltage support 3.3 to 5.5V DC Excellent long-term stability Fast-response and anti-interference capability Material: plastic colour: As Shown Package Contents: 2 x humidity module Probe 2 set accessories Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
