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 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, , humidity control and other application fields which need to detect and control temperature and humidity.Relative humidity and temperature outputSuperior sensor performance, typical accuracy RH: 2%, T: 0.3Wide voltage support 3.3 to 5.5V DCExcellent long-term stabilityFast-response and anti-interference capabilityMaterial: plasticcolour: As ShownPackage Contents: 1 x humidity module Probe1 set accessoriesOnly 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.
