SONOFF SNZB-02M AirGuard TH Pressure Zigbee Sensor – Temperature, Humidity & Barometric Pressure, Dew Point, VPD (Zigbee Hub Required)

Know your indoor climate and see weather changes coming. The SONOFF SNZB-02M AirGuard TH Pressure is a compact, screenless Zigbee sensor that measures five things at once: temperature, humidity, barometric pressure, dew point, and VPD. Readings refresh every 5 seconds, with accuracy of ±0.2°C for temperature, ±2% RH for humidity, and up to ±0.1 hPa for pressure. 🌡️💧🌤️

Pressure trend tracking helps you notice weather shifts, while dew point and VPD show moisture balance, helping you reduce condensation and mold risk and keep plants in comfortable conditions. Set comfort zones for temperature, humidity, and pressure, and get an instant alert when any reading leaves your range.

⚠️ Important Note
A Zigbee gateway is required, and it is sold separately. The sensor is for indoor use and is powered by a CR2477 coin cell battery, so please check the package contents for the included battery. ✅📡
