An IP56 RS485 Air Temp, Humi and Barometric pressure sensor has a wide operating range of 0-100% RH, -40 to 125°C, and 300-1100 hPa. It is ideal for applications such as smart agriculture, weather monitoring, calculating evapotranspiration, mold prevention and more. By integrating this sensor with the SenseCAP S2100 Data Logger, users can achieve seamless data collection and management.

This sensor accurately measures air temperature, humidity, and barometric pressure within the ranges of 0~100% RH, -40~125°C, and 300-1100 hPa. It is suitable for precise industrial environmental monitoring applications.

Furthermore, the sensor is compatible with a Solar Radiation Shield for Outdoor Sensor Protection, enabling waterproof and reliable outdoor measurements with minimized temperature buildup from solar heating.

The 3-in-1 integrated air temperature, humidity and barometric pressure sensor utilizes a SENSIRION temperature and humidity sensor and a BOSCH barometric MEMS chip for highly accurate, fast response measurements.

The sensing elements are compactly integrated onto a PCB located at the tip of the sensor, with dimensions of just 108mm x 16mm. This allows for easy installation and integration into existing systems as an expansion module. Each sensor is individually factory-calibrated before deployment. Based on direct measurements of temperature, humidity and barometric pressure, the sensor can calculate various meteorological parameters including vapor pressure, dew point, frost point, absolute humidity, vapor density, cloud base height and altitude. It has an RS485 communication interface with built-in surge protection for reliable data transfer. The sensor can be wall mounted or flange mounted for duct insertion.

With low power consumption, it is suitable for battery-powered systems. Reverse power and lightning protection further enhance robustness across various environmental monitoring applications.

The compact form factor combined with individal calibration, flexible mounting options and robust protection make this an ideal sensor for integrating accurate meteorological measurements into new or existing monitoring systems.

Recommendation for S2100 Data Logger

SenseCAP S2100 Data Logger can connect to MODBUS RS485/Analog/GPIO industrial sensors including the Grow Your Idea and transmit data from sensors to the LoRaWAN network. Benefiting from its high robustness and waterproof and dustproof enclosure, the S2100 data logger can work under harsh environments such as high UV exposure, heavy rain, dusty conditions, etc. which is ideal for outdoor use. Based on LoRaWAN, it can cover a long transmission range of 2km in urban scenes and 10km in line-of-sight while keeping lower power consumption. Equipped with built-in Bluetooth and app service for OTA configuration and remote management, it enables quick setup and update. It can be battery-powered or connected to a 12V external power supply. When the 12V power supply is connected, the replaceable built-in battery is set to be used as the backup power supply.
