The SMART METER Series is a high-precision temperature and humidity monitoring and alarm device based on GPRS wireless networking technology. With an attractive, robust, and reliable design, the device uses a standard GPRS RF transceiver and microprocessor, offering long-distance communication, strong anti-interference capability, and convenient networking.

The GPRS Temperature & Humidity Data Logger uses a dual power supply consisting of an external power supply and a built-in high-energy lithium battery, ensuring that recorded data is not lost and that the device can continue operating for an extended period in the event of an external power failure.

The temperature and humidity sensor is imported from Switzerland and features an over-molded protective design, which helps reduce the impact of external factors such as sensor aging, vibration, and volatile chemical gases. This ensures excellent stability and reliable measurement performance.

The typical temperature accuracy can reach ±0.2°C, while the typical humidity accuracy can reach ±2% RH, meeting the requirements for GSP/GMP-compliant applications.

Applications of the GPRS Temperature & Humidity Data Logger

The GPRS Temperature & Humidity Data Logger is widely used for continuous, 24/7 temperature and humidity monitoring in various applications, including:

• 24-hour temperature monitoring of refrigerators
• Online temperature monitoring for vehicle-mounted cold chain transportation
• Temperature and humidity monitoring in computer rooms and data centers
• Temperature and humidity monitoring in workshops and warehouses
• Other environments requiring continuous temperature and humidity monitoring
