This sensor allows you to use HRXL MaxSonar WR series ultrasonic sensors by MaxBotix
|
||
|
|
(`datasheet <https://www.maxbotix.com/documents/HRXL-MaxSonar-WR_Datasheet.pdf>`__)
|
||
|
|
with ESPHome to measure distances. Depending on the model, these sensors can measure
|
||
|
|
in a range between 30 centimeters and 10 meters.
|
||
|
|
|
||
|
|
This sensor platform works with the **TTL versions** of those sensors and expects the
|
||
|
|
sensor's TTL pin to be wired to one of the ESP's input pins. Since these sensors read
|
||
|
|
multiple times per second, filtering is highly recommended.
