1. What makes the DTH Modbus Sensor more reliable than other sensors?
2. Can it be used in high- temperature or high-humidity environments?
3. Is it easy to integrate with my system?
4. Can this sensor be used both indoors and outdoors?
The DTH sensor works in both environments, though it performs best when shielded from direct sunlight or rain outdoors.
5. How do I connect the sensor to my Pearl device or other controllers?
It connects directly via the I2C port or designated input on Link4 controllers, such as the Pearl and HydroRoot.
6. Is the sensor weatherproof and durable in harsh greenhouse conditions?
It is sealed and designed for high humidity and greenhouse use, though protection housing is recommended for extreme exposure.
7. What is the expected lifespan of the sensor in field/greenhouse conditions before replacement is needed?
Typically, the sensor lasts 3–5 years in greenhouse conditions, with replacement depending on exposure levels and maintenance.
