The HMATIX - ULTRASONIC is a security accessory that utilizes an HCSRO4 sensor. The system is coupled with a PIC12F1822, which managed the sensor and controls the relay. When the sensor received a signal indicating that an obstruction has pulse a reply signal, the relay activates and stays active so long as the obstruction is present.

Power Requirements

• DC / AC
• 7 Vdc Minimum

Sensor

• HCSRO4 ( 2CM to ~450CM)
• Plug and play operation

Operation

The operation is controlled via a PIC12F1822, which manages the interaction with the sensor.
