you might find Pico-compatible drivers for it in CircuitPython

Similar ultrasonic products may have frequent side lobe detection and can even falsely trigger on objects behind or to the sides of the sensor

They are third-party tested for the equivalent of 10+ years of UV exposure in addition to thermal cycling

Industrial Leaf Wetness and Temperature Sensor _HA_WAVE This is the Adafruit FeatherThe Leaf Wetness and Temperature Sensor tracks moisture and heat on plant surfaces to help farmers prevent disease and control irrigation timing. Leaf wetness is an important indicator of the infection of pathogens on the leaves. The amount of moisture on the leaf surface makes it easy to be infected by fungal and bacterial diseases. It is used for monitoring leaf moisture for agricultural purposes, such as fungus and disease control, for control of
