UbiBot UB-LTH-N1 Wifi Temperature Sensor
Toote tutvustus
The temperature sensor consists of a high-precision thermistor and a transmitter that accurately measures the temperature over the entire range. The humidity sensor is based on the dielectric constant measurement principle, which simulates the shape of the blade and the characteristics of the blade surface. Humidity can be measured accurately by the change of dielectric constant on the blade surface. With good sensitivity, it can detect trace moisture residues on the leaf surface. The leaf surface temperature and humidity transmitter adopts waterproof design, low power consumption, and can be continuously monitored for a long time.
Kasutage juhtumistsenaariume
The sensor is suitable for measuring humidity on the surface of plants or objects in greenhouses, laboratories and artificial climate chambers.
Omadused
- Mimics the characteristics of leaf surfaces for fast and accurate temperature and humidity measurements.
- Denser leaf vein pattern (15 lines/cm) allows detection of smaller droplets for more sensitive measurements.
- Epoxy resin encapsulation, waterproof and moisture-proof, longer life.
