5V RS485 Soil Temperature & Miosture probe for WS1 Pro; 3M lead, USB plug

Soil Temperature and Moisture Sensor

Monitoring the soil temperature and humidity with embedded RS485 interface

Teknisk funktionsbeskrivelse

Dette produkt anvender modbus-RTU protokollen og computeren kan således overvåge såvel temperaturen som jordens fugtighedsniveau via dens indbyggede RS485-interface.

Fabrikantens tekniske forklaring på selve måleprincippet i proben kommer her (på engelsk):

We think of the soil as a capacitance containing a medium according to transmission line theory the circuit due to the load impedance mismatch appear under a certain frequency resonant migration reflection amplitude value is not the same at the same time through comparing the difference of reflection wave and the incident wave amplitude value measure the capacitance of the multiple reflection wave caused by the changes and then measure the soil moisture content. The probe shell is made of ABS which has good resistance to acid and alkali corrosion. The shell is completely wrapped and can reach the IP68 waterproof level which means that the probe can be continuously measured in water.

Soil-proben kan benyttes sammen med WS1-Pro loggerne.
Måledataene kan aflæses/overvåges på enten computerplatformen eller via mobil APP’en.

Anvendelsesmulighedder
Proben anvendes oftest såvel i private hjem som på kontorer samt naturligvis i landbrug og gartnerrier og andre steder hvor måling og overvågning af jordtemperatur og jordfugtighed ønskes.
