Soil & Water PH and Temperature Sensor (RS 485-Industrial Standard IP68)

From the shop's description

This is an industrial grade soil and water PH and temperature sensor. The new generation Ph sensor can measure pH and temperature level in both soil and water as well. Soil and water pH is a measure of the acidity or alkalinity of the soil or water. Soils (or water) can be classified according to their pH value where 6.5 to 7.5 is neutral soil (Ideal soil for growing plants), over 7.5is alkaline and less than 6.5 is acidic. The sensor has RS 485 serial interface with 2-meter cable which can be extended to 1000 meter without affecting measured data quality, thanks to RS 485 long distance serial communication interface. It can be integrated with GPRS/4G/WIFI/LORA wireless module. Specifications Operating Voltage: 5-24V. Output: RS485, MODBUS communication protocol PH Measurement range: 3～9 PH PH Resolution: 0.01 PH PH Accuracy: ±0.2 PH Temperature Measure range: -40~85℃ Temperature Resolution: 0.1℃ Temperature Accuracy: ±0.4℃ Protection Isolation: Up to four isolations, power isolation, protection grade 3000V Standard cable length: 2 meters Anti-corrosion stainless steel probe Protection level: IP68 Soil and water PH and Temperature sensor manual.
