Identifying the Sensor for Detecting Nearby Objects

In the context of sensors that can detect nearby objects, let's analyze the options provided:

1. Touch Sensor: This sensor detects physical contact. It is activated upon being touched, but it does not detect objects at a distance.

2. Pressure Sensor: This sensor measures the pressure applied to it but does not inherently detect objects unless they exert pressure on it directly.

3. Humidity Sensor: This sensor is designed to measure moisture levels in the air and is not capable of detecting objects.

4. Proximity Sensor: This sensor detects the presence of nearby objects without physical contact. It uses various technologies (like infrared or ultrasonic) to sense the distance or presence of objects.

Conclusion

The correct answer is d. Proximity sensor, as it is specifically designed to detect nearby objects.
