Instructions for Using MB3752:

1. Power Supply:

   • Connect the Vcc pin to a power supply within the range of 2.0V to 5.5V.
   • Connect the GND pin to the ground of the power supply.

2. Output Connection:

   • The output is an open collector type, which means it can sink current but not source it.
   • Connect a pull-up resistor (typically 1kΩ to 10kΩ) between the output pin (Vo) and Vcc.
   • Connect the output pin to the input of your microcontroller or other device.

3. Detection:

   • The sensor will detect objects within a range of 0 to 50 cm.
   • The output will be low (Vo ≈ 0V) when an object is detected.
   • The output will be high (Vo ≈ Vcc) when no object is detected.

4. Response Time:

   • The sensor has a typical response time of 100 ms. This means it may take up to 100 ms to change its output state after detecting or losing an object.

5. Operating Temperature:

   • Ensure the sensor operates within the temperature range of -20°C to 70°C for optimal performance.
   • Store the sensor in temperatures ranging from -40°C to 85°C.

6. Mounting:

   • Mount the sensor in a stable position with a clear field of view for accurate detection.
   • Avoid placing the sensor near sources of electromagnetic interference (EMI).

7. Testing:

   • Before deploying the sensor, test it in the intended environment to ensure it meets the required detection criteria.
   • Use a multimeter to verify the output voltage levels when an object is present and absent.
