We offer a variety of wired / wireless solutions: residential and building intelligent control system\ Wireless smart home solution
·Wireless gas water heater
In the process of incomplete combustion, gas is easy to produce carbon monoxide, and human body will be poisoned if inhaled too much. Therefore, gas water heaters are required to be installed outside the balcony / bathroom. Because the temperature cannot be adjusted when taking a bath, it is very inconvenient to go out of the bathroom to the water heater when it needs to be adjusted; The wireless water heater control scheme solves the disadvantages of the traditional water heater, which has the following characteristics:
1. No wiring and more convenient installation;
2. When taking a bath, you can adjust the temperature at will, which is more comfortable and intelligent;
In this scheme, TI MSP430F4152 + CC1101 is used to realize wireless control of water heater,
It has the characteristics of low power consumption and long control distance.
《Main parameters as follows》:
1. Working voltage of remote controller: 2.0-3.6v
2. 433MHz communication frequency, communication distance 250m
3. The operating current of the remote controller is less than 30mA
4. Standby power consumption < 100ua
