MEMS Temperature and Humidity Sensor Module ZS11

  • ZS11.png


ZS11 is a brand new product equipped with a dedicated ASIC sensor chip, a high-performance semiconductor silicon-based capacitive humidity sensor and a standard on-chip temperature sensor, and uses a standard I²C data output signal format. ZS11 products have stable performance under high temperature and high humidity environment; at the same time, the products have great advantages in accuracy, response time and measurement range. Each sensor has been strictly calibrated and tested before leaving the factory to ensure and meet the large-scale applications of customers.


* Fully calibrated
* Wide supply voltage range from 2.2V to 5.5V
* Digital output, IIC interface
* Quick response and strong anti-interference ability
* Excellent long-term stability

Vehicle Air Quality

Vehicle exhaust contains hundreds of different compounds, including suspended solids, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. Among them, hydrocarbons (HC) in automobile exhaust are the result of direct emission of unburned or insufficiently burned gasoline in the form of gas. Under the action of ultraviolet light,
