At this point, a rather expensive sensor for around >36€, but one that beats the other distance sensors by „lengths“. I actually wanted to test the I²C version, but the UART version arrived here, which is why I'm presenting it now. (Since I couldn't find any documentation, I'm still not sure if I²C wouldn't also be possible. 🙂)

This laser distance sensor is faster than sonar sensors such as (for example, HC-SR04, US100). It measures in the range of 30mm up to 2 metres and is controlled via the I²C bus at address 0x29. The address can be changed via software.

The US-100 is an ultrasonic distance sensor with a supply voltage of 3V – 5V. It can therefore be operated directly with modern microcontrollers with a 3.3V supply voltage. Views Facts Technical Data Pin Assignment Supply Voltage 3-5V Trigger Echo Ground Ground Special Features The US-100 can be operated in two modes. In serial mode, the jumper on the back is set. …

The HCSR-04 is a widely used and correspondingly inexpensive distance sensor. It determines distance using ultrasound and is easy to operate with common 5V microcontrollers. The datasheets contradict each other regarding the maximum distance specification, fluctuating between 3 and 4 metres. I haven't yet had a module in my hand that reached 4m. With …

It has low power consumption and is inexpensive to purchase. General Technical Data Pin Assignment Supply voltage 5V Trigger Echo Ground Similar Sources Tech Blog

Here, some distance measuring sensors are to be presented. This list does not claim to be exhaustive. Only the sensors that I am currently using in my projects are described. Comparison Here is a direct comparison; further details can be found in the individual sections below. Ultrasonic sensors Ultrasonic sensors emit a sound pulse and then wait for a reflection of the pulse…
