Detection angle:<15 °
Using industrial grade MCU, operating temperature : -20 ℃~80 ℃
Detection distance: 5V: 2cm-450cm; 3.3V: 2cm-400cm
Wide voltage operation: 3V-5.5V is fully compatible with HC-SR04 software and hardware dimensions
On board wiring methods, VCC, trig (control end), echo (receiver end), out (empty pin), GND
Note: The TRIP pin is an internal resistor that pulls up 10K. Use the IO port of the microcontroller to pull down the TRIP pin and then give a pulse signal of more than 10us.
The OUT pin is the switch output pin of this module when used as an anti-theft module, and the ranging module does not use this pin
Attention: The module should be plugged into the circuit board before being powered on to avoid high-level misoperation. If it occurs, it can be resolved by re powering on.

I tried two older 5v sensors. They seemed flakey with my 3.3 Pico. These sensors, that work with both 3.3 and 5v, work great.

These are great inexpensive distance sensors. These are ideal for monitoring the perimeter of close objects. I recommend adding a lidar distance sensor as well so you can accuratly measure distances. Lidar measures to a single point, even at a distance, whereas these sonar sensors measure an ever widening cone. This means that they become less accurate as more obstacles show up in that cone. Enjoy.
