Sonoff Air Pressure Sensor Zigbee Temperature Humidity Barometric Smart Home Indoor Weather Monitor APP Alert Office SNZB-02M

Introduction

The SNZB‑02M is a low‑power, screenless temperature, humidity, and barometric pressure sensor that provides real‑time, precise monitoring of ambient temperature, humidity, and air pressure data.

The device supports both adhesive and magnetic mounting for quick and convenient installation. When used with a Zigbee gateway, it offers features such as barometric pressure calibration, unit switching, and comfort level settings.

It can also be integrated into smart scenes through automation, enabling automatic environmental adjustments to keep you in a comfortable, livable space at all times—delivering a subtle yet seamless smart living experience.

Highlights:

● 【5-in-1 Monitoring】 – Precisely measures five key environmental indicators: temperature, humidity, barometric pressure, dew point, and VPD (Vapor Pressure Deficit). Features temperature accuracy of ±0.2°C, humidity accuracy of ±2% RH, and barometric pressure accuracy up to ±0.1 hPa. Data refreshes at a high frequency of every 5 seconds, capturing even the slightest environmental fluctuations with precision.

● 【Barometric Pressure Monitoring】 – High-precision detection of minor pressure variations. Leverages pressure trend analysis to anticipate weather changes, helping you proactively prepare for rainfall, pressure-induced discomfort, and other conditions.

● 【Dew Point & VPD】 – Accurately calculates dew point and VPD values to quantify environmental moisture balance, effectively preventing condensation and mold risks. Ideal for specialized applications such as plant cultivation, indoor moisture control, and other professional scenarios.

● 【Smart Scene Automation】 – Supports automatic trigger of smart scenes based on changes in barometric pressure, temperature, and humidity individually. Seamlessly integrates with fans, humidifiers, ventilation systems, and other devices for automated environmental regulation.

● 【Triple Comfort Alerts (Temperature, Humidity, Pressure)】 – Supports customizable multi-dimensional comfort zones combining pressure, temperature, and humidity. Instant push notifications are triggered when any indicator exceeds preset thresholds, keeping you informed of pressure changes and real-time comfort status.

● 【Cloud Historical Data Storage】 – Full-spectrum environmental data backed up to the cloud with up to 6 months of free storage. Exportable historical records of pressure, temperature, and humidity enable trend analysis and environmental assessment.

● 【Long Battery Life】 – Powered by a CR2477 battery with ultra-low-power design, delivering over 2 years of battery life—eliminating the hassle of frequent replacements.

● 【Zigbee 3.0 Compatibility】 – Seamlessly compatible with SONOFF iHost, NSPanel Pro, ZB Bridge Pro, and other Zigbee gateways. Also supports third-party Zigbee hubs including Echo 4th Gen, SmartThings Hub V3, and more.
