Product Summary: consists of an all-new-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 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, , 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: 1 x humidity module Probe 1 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.
