Infrared-Human-Sensor
This infrared motion sensor reference design uses an infrared sensor to detect the presence/absence of a person and automatically turns a high-brightness LED on or off. It is applicable to a wide range of applications including office lights and automatic doors.
The infrared LED transmit signal is controlled by the timer array unit (TAU01) of the Renesas RL78/G10 microcontroller, while the receive signal is controlled by the timer array unit (TAU00) and external interrupt pin (INTP0). When a person is detected, a high-intensity LED turns on; when the person leaves the detection area after 10 seconds, the LED turns off and the system enters STOP mode for the infrared receive signal. The RL78/G10 offers the industry's lowest current consumption, making it ideal for human body detection.
The infrared human detection sensor solution uses the RL78/G10, a 10-pin LSSOP package general-purpose microcontroller. The sensors are inexpensive and save energy. It is ideal for temporary lighting of entrances, porches, stairs, and bathrooms. For example, the bulb turns on when a person approaches and automatically turns off when the person leaves.
