Product Descriptions

AM2305B 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 generations. The new 

generation sensor module has a more stable performance in harsh environment. At the same time, AM2305B has higher cost-effectiveness and 

applicability, due to the improvement from miniaturization. Each sensor is strictly calibrated and tested to ensure its high quality.

Product Features&Applications

• 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

The AM2305B 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, 

medical and other application fields which need to detect and control temperature and humidity.
