Ra-08/Ra-08H LoRaWAN module by Ai-Thinker

Ra-08/Ra-08H is a LoRaWAN module base on the chip ASR6601, which is designed by Ai-Thinker.

The difference between Ra-08 and Ra-08H is that they are support different frequency: 410MHz-525MHz & 803MHz ~930MHz.

LoRa for Smoke Sensor

Here, let’s talk about the smart smoke sensor. At present, the smoke alarm application is popular and received high attention as the frequent occurrence of fires.

Ra-08/Ra-08H module can be well-used in smart smoke sensor due to it support long-distance communication, ultra-low power consumption, high sensitivity, etc.

With the development of intelligent firefighting, wireless intelligent smoke sensor has begun to replace traditional smoke sensor.

This enables remote monitoring of the fire.

Wireless intelligent smoke sensor has the advantage of easy installation , no need to do any wiring. With various and timely alarms, intelligent supervision is possible.

The LoRa smoke sensor can be directly connected to the network through the gateway, and the wired network can be used for data transmission or even a small monitoring host can be installed to build a network.

The average power consumption of using LoRa smoke detectors is relatively low, that is why, they can even be powered by battery.

Such a LoRa solution’s smart smoke sensor can be used in a wide range of places, which can greatly reduce the occurrence and loss due to fire disasters.
