Description

The HC-SR04 module measures distance to objects by means of ultrasonic reflection. This is done by firing pulses of 40 kHz to the environment, after which the time required to receive the reflected signals is measured. By dividing this time by a constant, the distance can be determined fairly precisely (up to 0.3 cm precision!). Works with all hard surfaces (the sound must be able to be reflected).

I use this sensor in my rain reservoir to measure the level of rain water and the humidity is apparently a problem. The measurement fails after a few months. The interior works fine.
