What is the principle of wireless water sensor?
A water sensor, also known as a water leak sensor, is a sensor that can detect in real time whether a water leak has occurred within the measured range, and once detected, it will immediately issue an alarm. Because the water sensor can achieve intelligent water leakage monitoring, greatly saving labor costs, and timely prevent related losses caused by water leakage accidents, it has been gradually applied to important places such as computer rooms, warehouses, factories, museums, archives and so on in recent years. With the development of Internet of Things technology, the current water sensor is also divided into wired and Lora/NB wireless water sensor. Today to talk to you about Lora/NB wireless water sensor principle is what? What brand of water sensor is good?
The traditional water sensor, using the wired transmission method, has the advantage of stability and durability, but the disadvantage is that it needs to leave space for complex wiring, and the transmission distance is limited. Therefore, in order to meet the needs of water leakage monitoring in different scenarios, wireless water sensors have been gradually applied. Wireless water sensor commonly used transmission methods are Lora wireless water sensor and NB-IOT wireless water sensor.
The principle of Lora wireless water sensor is similar to the wifi we usually use, the sensor layer device realizes data transmission through the LORA chip, and its networking architecture is: LORA sensor layer device (sensor), LORA gateway, server, and service terminal. The advantages are long transmission distance, low power consumption, many networking nodes, strong anti-interference, good data confidentiality, low maintenance and later use costs.
The principle of NB-iot wireless water sensor is similar to the mobile phone, the sensing layer device needs to install an NB traffic card to transmit data, and its networking architecture is: NB sensing layer device (sensor), NB base station, NB device data storage server and terminal service platform. The advantages of NB are: wide coverage, large depth, low power consumption, low cost, and large connection volume.
