Process: When the infrared sensor senses that someone is approaching, a signal is output to the control circuit, and the control circuit sends a control signal to the solenoid valve motor to flush the water for a short time; When someone leaves, the infrared sensor outputs a signal to the control circuit, and the control circuit sends a signal to the solenoid valve motor to flush for a long time.
The relationship with single-chip microcomputer: the control circuit can be used as the core, the frequency signal of infrared sensing can also be provided by the single-chip microcomputer, and the length of flushing time can also be timed by the single-chip microcomputer, so the single-chip microcomputer can be used to do the input, output and time control of the flushing system.
If there is a professional design, it can be constructed according to the drawings.
* Motherboard adopts digital circuit, digital transmission, 16-bit digital is more accurate. >>>More
Theoretically, it is possible, when someone approaches, a relay signal output is triggered, and an external siren horn can be connected. But I don't know if you've noticed, that thing's sensing distance is very limited, is there twenty centimeters? It is not practical, and the sensing distance of infrared probes on the market is at least about ten meters.
Hello. It is an automatic flush controlled by the clutch. >>>More
Infrared induction flusher, the principle of infrared light reflection is applied, people stand in front of the urinal (squatting toilet), the infrared light emitted by the infrared emission tube is reflected to the infrared receiving tube through the human body, and then the signal is controlled by the follow-up processing to open the water through the solenoid valve. >>>More
