It is based on ZigBee protocol make serial transmission module, under serial data wireless data transmission, we also added some features, including remote ADC sampling, remote PWM wave output control, remote control of GPIO. Users do not need to understand the complex wireless communication principle, just send a simple control instructions can realize data transmission and intelligent control

Advantage

Small Sise: 18.1*12.5

Working Temp.: -40 ~ 85 degree

Long distance, high transmission rate

Set of coordinator, router, terminal, three heavy equipment in one

Support automatic power network, network parameters are not easy to lose, self healing, strong networking ability, stable network, reliable

Automatic routing, remote data, don't worry

Support data encryption transmission. Secure. (data encryption transmission needs of every equipment are provided in the same key)

The network structure can be viewed and the network status is clear

Function

1 Serial data transmission

The main function module is a serial data transmission for wireless users, the hardware solution for wireless communication. Support network communication, automatic routing, network maintenance. Is a very suitable for use in intelligent Home Furnishing, intelligent agriculture, intelligent super, wireless communication module design of intelligent hardware field

2 PWM output

The module has local and remote PWM output capability, each module has 3 PWM wave, independent of each other, the duty cycle is set at random, motor speed regulation, light shading, color control of seven color lamps

3 GPIO controller

Module has the ability to local and remote control, it can help you save outside control the MCU, , directly to your device is connected to the specified pin module, sending simple commands, you can achieve remote control. The module supports 8 GPIO independent control of each other.

4 ADC acquisition

Module with local and remote ADC acquisition ability, 8 channel ADC enough you use the 13 bit sampling rate. Superior precision will connect you to the analog sensor module, the sensor data will be presented in front of you, with the remote GPIO, intelligent automatic control, so simple.
