This RS485 sensor is designed to precisely measure air temperature, humidity, and barometric pressure to a 0-100% RH, -40-125°C, and 300-1100 hPa range respectively. It is suitable for industrial applications that require precision readings.
The S-THP-01A has been constructed to maximize accuracy in outdoor measurements when used with a solar radiation shield. This shield ensures both waterproofness and guards against a temperature increase due to solar radiation.
Feature
- High Performance: High accuracy, fast response, good repeatability
- 3 in one sensor: Humidity/Temperature sensor and BOSH barometric sensor
- Based on the data directly measured by the sensor, relevant common meteorological parameters can be calculated including vapor pressure, dew point, frost point, absolute humidity, vapor density, cloud base height, and altitude.
- Universal Protocol: RS485 communication interface with surge protection
- Reverse power protection and Built-in TVS/ESD protection
Description
The S-THP-01A offers an integrated solution with a SENSIRION® temperature & humidity sensor and a BOSCH® barometric MEMS chip for fast and precise air temperature, humidity and barometric pressure measurements.
The S-THP-01A boasts a robust design, with its sensing elements tightly integrated onto a PCB at the tip, measuring just 108mm x 16mm. This allows for seamless installation and expansion into any existing system. The factory-calibrated sensors measure temperature, humidity, barometric pressure and more, delivering various meteorological parameters - such as vapor pressure, dew point, frost point, absolute humidity, vapor density, cloud base height and altitude - with precision to the RS485 communication interface and built-in surge protection for reliable data transfer. The sensor can be mounted on walls or flanges 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.
Seeed also provides the SenseCAP Portal and SenseCAP Mate to help users better manage and check data remotely.
