Audited Supplier | Smart Combustible Gas Alarm with Remote Control |
The GDA-TW combustible gas detector (LoRaWAN) is a high stability combustible gas detector (hereinafter referred to as the detector), which is used to detect the leakage of combustible gas. The detector adopts advanced semiconductor gas sensor, which has stable operation, long service life and simple installation. The detector has a built-in MCU for central control processing, and each functional block is directly or indirectly connected to the I/0 port line of the MCU. The normal work of each functional module of the detector is completed through the program solidified in the MCU, so that the detector works more stable, safe and reliable. This product is suitable for safety monitoring in places where combustible gas exists, such as family residences, real estate villas, hotels and apartments.
1.Small size and strong applicability.
2. The product itself has waterproof function.When the water level is higher than the leakage alarm, the water immersion detector will automatically float on the water surface.
3. Active upload: when water leakage and battery undervoltage are detected, the data will be actively uploaded to the corresponding platform through the LoRaWAN wireless network;Upload normal information (heartbeat) every 24 hours (settable).
4. ABS plastic has the function of high temperature resistance and low temperature resistance to adapt to more environments.
5. High reliability sensor.
6. Automatic reset.
7. Adopt microprocessor control.
8. Automatic fault detection indication.
9. Detection of natural gas, liquefied petroleum gas, etc.
10. Active upload/two-way transmission function:The data will be actively uploaded to the corresponding platform through the LoRaWAN network when alarm occurs. Upload normal information every 24 hours(settable). Real time response to instructions issued by the platform.
| Smart Wireless LoRaWan Infrared Sensor Alarm |
The smart infrared sensor alarm uses a dual-element infrared digital probe. It has the characteristics of high input impedance, high power supply rejection ratio, strong anti-radio frequency interference, and low power consumption. It can cooperate with the microprocessor to realize different application scenarios, and has two modes: intrusion monitoring and nursing monitoring (alarm when unattended). Support remote control through wireless LoRaWAN network communication. Support to build intelligent IoT network together with LoRaWAN gateway and TimeWave IoT platform. And realize scene linkage with other smart devices.
1.Dual-element digital infrared probe with high reliability;
2.It adopts SMD technology and is good anti-radio frequency and anti-white light interference.
3.Three modes are optional: normal mode for intrusion monitoring, smart mode for intrusion monitoring, and nursing mode (alarm when unattended in 8/12/22 hours);
4.LoRaWAN wireless communication. Support alarm push from server, WeChat official account, phone and SMS;
5.GNSS reports position information, which facilitates the integration of pathing and scheduling task planning systems;
