Mounting a sensor with two transducers can be difficult and often requires tiny screws, whereas the MB1240 has two holes for M3 bolts. For me, the major advantages of the MaxBotix sensors are the automatic real-time calibration, small beam angle, high noise tolerance, and onboard filtering. ...
it probably doesn’t have Wi-Fi coverage. So, you can build a sensor node with an ESP32 and a moisture sensor, that sends the moisture readings once or twice a day to another ESP32 using LoRa.
