Humidity Sensors

SKU: AF-3721 | Brand: Adafruit

The AM2320 is a low-cost digital temperature and humidity sensor with an I2C interface — a simpler alternative to the classic DHT11/DHT22 sensors that require timing-critical bit-bang protocols. With standard I2C comm...

SKU: DF-SEN0233 | Brand: DFRobot

A multifunction air quality monitor that measures particulate matter (PM2.5), formaldehyde concentration, temperature, and humidity. It uses laser scattering to detect suspended particles in the air, an electrochemica...

SKU: DF-SEN0148 | Brand: DFRobot

This is an anti-rust, robust and precise SHT10 sensor, which can master enterprise-class and industrial-level applications. It can be applied in various fields: telepoint base stations, electronic control cabinet, pr...

SKU: AF-3251 | Brand: Adafruit

The Adafruit Si7021 is a temperature and humidity sensor from Silicon Labs with a PTFE filter for protection against dust and contaminants. It provides ±3% relative humidity accuracy over 0–80% RH and ±0.4 °C temperat...

SKU: AF-1899 | Brand: Adafruit

The Adafruit HTU21D-F is an accurate I²C digital temperature and humidity sensor breakout board. With typical humidity accuracy of ±2% (optimised for 5–95% RH) and temperature accuracy of ±1°C across -30 to 90°C, it's...

SKU: DF-SEN0678 | Brand: DFRobot

This Gravity air quality module uses Sensirion’s STCC4 gas sensing chip to directly measure carbon dioxide with the thermal conductivity measurement principle. It is designed for compact, cost-effective indoor monitor...
