It uses two TWH8778 switch integrated circuits Ai and A2. When the voltage of the TWH8778
g control terminal is higher than 1. 6V, the TWH8778 is turned on, otherwise it is turned off.
This circuit can be used for light control and temperature control in chicken houses. It has the function of automatically turning on the lights when the light dims, and automatically starting
the electric heater when the temperature inside the house drops. The light control is controlled by the photoresistor RG, and the temperature control is controlled by the thermistor Ri with negative temperature coefficient.
