The GL-TV Uni sensor is an integrated IoS Bluetooth LE 5.2 sensor platform powered by two independent Li-SOCI2 batteries, providing long-term and reliable data transmission from sensor sensors in the harshest conditions.
GL-TV Uni is a multi-sensor wireless platform with a magnetic field sensor (hall sensor), temperature sensor, light sensorr. Multiple spanning capabilities support a wide range of use cases, and its IP67 enclosure provides reliable protection even in the harshest conditions. The display and output of information can be carried out using various monitoring and telemetry systems, smartphones, as well as using the universal BLE indicator GL-TV Tab.
Design and functionality of the sensor:
|
• The presence of an external antenna for stable operation inside refrigerators, refrigerators, thermowells (from other closed metal objects); |
|
• Magnetic field sensor - magnetic reed switch; |
|
• Light sensor; |
|
• External constant voltage monitoring; |
|
• IP67 housing; |
|
• High capacity of two batteries, duplication of power supply, it is possible to replace batteries at the end of their service life; |
|
• Temperature control: built-in temperature sensor, with the possibility of offline connection of an external DS18b20 sensor; |
|
• LED operation indication; |
|
• Linearity of measurements, high accuracy |
Advantages of the GL-TV Uni Wireless Universal Sensor:
- Absence of wires and cables due to the use of the Bluetooth LE radio channel
- Wide range of applications (temperature sensor, reed switch, light sensor)
- Easy setup via mobile app and quick installation
- Stable communication due to the use of two types of antennas
- Autonomous power supply for 6 years or more
- The best replacement for wired temperature sensors
Extensible functionality of GL-TV Uni :
1. Support for external temperature sensors on the DS18B20 chip.
2. External measurement of the DC voltage level.
