internal SHT30 I2C output
Main Features:
Four-core connector, easy to replace and maintain. If the accuracy is insufficient, the sensor can be replaced at any time.
Usage: The probe can be directly buried in the soil.
Info
Product Features:
- Digital, resolution up to 14 bits

Application range:
Application range:
- Computer room monitoring
- HVAC
- Weather station
- Warehouse
- Construction site
- Concrete test block detection
- Agricultural greenhouse
- Flower Nursery
Data loggers, transmitters, automated process control, construction sites, agricultural greenhouses, flowers, nurseries, lawns, and other environments where soil temperature and humidity need to be measured. The metal-encased form factor is more suitable for use in environments with significant dust and harsh conditions.
