Aiming at the problems of low upper limit of temperature measurement, high power consumption, low transmission rate and the like in the traditional temperature detection system, the GPRS multi-point wireless temperature sensor acquisition and monitoring system further improves the measurement accuracy of the system, and the test results show that the system has high accuracy, sensitivity and practicability. The traditional multi-point temperature detection technology generally uses infrared or integrated temperature sensors, and adopts wired transmission mode. The laying and maintenance costs of remote lines are too high and the lead wires are too long, which leads to slow transmission rate, increased power consumption and decreased stability of the whole system. Wireless  GPRS temperature sensor   adopts wireless transmission mode. Wireless wiring doesn’t need to change the building structure, with simple installation, low power consumption components and low comprehensive co...

Alarm mode of  GPRS temperature sensor : alarm system of   GPRS temperature sensor  can simultaneously monitor the changes of measured values of digital temperature sensors, temperature, humidity, voltage, current, pressure or other types of transmitters. It has wired triggering and wireless triggering alarm functions. It can also be equipped with MMS camera, power on air conditioner automatic starting module, power off / power on, smoke, flooding, entrance guard and other detectors to expand its application range. When any alarm occurs, the alarm system will send an alarm short message to the mobile phone-Apple or Android mobile phone and the alarm monitoring center to describe the alarm reason, and dial the preset alarm receiving mobile phone number in turn.  The alarm receiving personnel can judge the alarm reason and location through monitoring data and short message content. The alarm monitoring center can display the alarm location on the map. The alarm system ...

GPRS temperature and humidity sensor is a new type of transmitter (compare with GPRS temperature sensor). On the basis of retaining the original sensor function, a module is added. It is no need to wire and monitor the computer on site, which is similar to  GPRS temperature sensor . SIM card can be inserted into the module and the data can be uploaded directly to the server and mobile phone with IP address set in the software. The power failure alarm can automatically and regularly transmit real-time data and historical data to the server of the management system. Functions and Characteristics of GPRS Temperature and Humidity Sensor; On - site real-time display and recording of temperature and humidity changes on site. Large screen display, simple operation and reliable performance. GPRS transmission mode is adopted without field wiring. Adopt digital sensor, data integration with high precision. Data can be uploaded to the data server regularly. According to the requirements of us...
