High-Reliability Temperature and Humidity Sensor - MHT04H

The high-reliability temperature and humidity sensor - MHT04H is an industrial-grade integrated temperature and humidity acquisition sensor, featuring a dustproof, waterproof, and breathable platinum stacked humidity-sensitive probe combined with a high-precision capacitive conditioning chip MDC04 architecture. It supports digital single-bus output, can be connected in series over long distances with multiple nodes, resists chemical gas interference, and withstands high-humidity environments. It is suitable for high-humidity farming, grain condition monitoring, and industrial environments with chemical gas corrosion, dust, and easy condensation.

MHT04H is an upgraded version of the Minsource temperature and humidity module MHT04/MHT04-IIC. To prevent interference from salt crystallization, water mist, etc., a waterproof and breathable membrane is wrapped around the humidity-sensitive capacitor. For high-humidity corrosive environments, epoxy resin protection is coated on the humidity-sensitive capacitor and MDC04 pins.
