IoT application environment parameters (temperature, humidity, light, carbon dioxide, pressure, infrared, etc.) wireless ZigBee monitoring system Beijing Shengshi Hongbo Technology Co., Ltd. Description:
The most commonly used is the RS485 bus communication technology using the Modicon protocol. The environmental monitoring points are connected in series through the 485 bus and finally connected to the computer. However, since not every occasion is suitable for wiring, most areas are based on the times. The demand for advancement in science and technology has only started to monitor the environment of the Internet of Things. The secondary wiring will be more troublesome. Beijing Shengshi Hongbo Technology Co., Ltd. specially developed wireless ZigBee wireless technology instead of the 485 bus based on market demand. Environmental monitoring system, instead of the traditional form of routing, for the majority of customers not only saves costs, but also too high grade.

Wireless ZigBee environmental monitoring system development diagram:
The following uses the temperature and humidity as an example to expand:
1. Single multi-point measurement 2. Multi-point multiple or single measurement 3. Single-point measurement diagram Simple explanation:
The terminal for measuring and controlling the environment of the Internet of things is a variety of sensors, transmitters, and detectors; for example, temperature sensors, humidity sensors, temperature and humidity sensors, light sensors, and carbon dioxide sensors. (Another prerequisite is that all sensor outputs The signal must be: RS232 or RS485 digital signal, not a digital signal can add the collector to convert), the sensor outputs a signal directly to the wireless ZigBee module, the sensor and the wireless ZigBee device is a wired link, the sensor and the wireless ZigBee device is connected, Connect to power.
The system monitoring center is equipped with a wireless ZigBee receiving device to receive the data sent by each wireless ZigBee module. At present, the upper limit of the transmission distance between single-point linear obstacles is 1.6 km. If the distance is relatively long and the number of points is relatively large, methods are used. There are two kinds, one is to add repeaters, and the other is to use wireless ZigBee devices as a relay function to implement point-to-point interconnection and point-to-point interworking, so that if there are 10 wireless monitoring points, the upper limit is It can be increased to 16km. The number of walls can be increased to 10 or more. The single-point wireless device has a wall capacity of about 3 walls.
