The Industrial MODBUS RS485 Air Temperature and Humidity Sensor is a rugged climate probe designed for accurate and reliable environmental monitoring in demanding conditions.
With a wide measurement range of -40°C to +80°C and 0–100% RH, it delivers high-precision data collection with fast response and long-term stability.
Engineered for industrial and outdoor applications, this sensor comes in two variants to suit different setups: a hook-up wire version compatible with the SenseCAP LoRaWAN® Data Logger for low-power, long-range connectivity, and a waterproof aviation connector version designed for the SenseCAP Sensor Hub 4G Data Logger, enabling multi-sensor data collection via 3G/4G LTE networks.
Its robust, waterproof, and dustproof design ensures dependable performance under harsh conditions such as strong UV exposure, heavy rain, and dust.
When paired with a Solar Radiation Shield, the sensor provides even more accurate outdoor measurements by preventing temperature buildup.
Built for seamless integration, the sensor works with SenseCAP S2100 Data Logger and S2110 Grove Converter, making it easy to deploy in LoRaWAN networks or extend existing setups with Grove sensors.
Combining industrial-grade durability, energy efficiency, and flexible connectivity, this sensor is an ideal solution for agriculture, smart cities, environmental monitoring, and other industrial IoT applications.
