The of TRUEBNER developed and manufactured SMT50 is a particularly inexpensive FDR soil moisture sensor.
Compact, functional and robust: The glass fiber reinforced circuit board enables a cost-effective design and easy installation thanks to the blade shape. The housing and cable are waterproof.
The SMT50 has a large measuring range. It is maintenance-free and frost-resistant. With its short measuring time and the low influence of salinity, it is suitable for continuous use.
Soil moisture and temperature are output as voltage signals.

Ordering process and delivery excellent. Quality and readings are (so far) as described and expected. However, such a product can hardly be judged conclusively a few days after purchase.
