Soil Npk Ph Ec Temperature Moisture 7 In 1 Sensor

This 7 in 1 integrated soil nutrient sensor can measuresoil moisture, electrical conductivity, temperature, nitrogen, phosphorus, potassium, and pH,7 elements at the same time. It can be used for long-term and stable measurement of soil conditions in a fixed area at a cheap price. Using RS485 Modbus standard protocol, the signal is stable.This 7 in 1 soil nutrient sensor solves the problem that users need to purchase multiple soil sensors to measure different soil elements. It consists of five stainless steel probes, which are used to measure soil moisture, temperature, electrical conductivity, NPK, and pH. You can select one or more soil elements to measure or test all soil elements at the same time. The flexibility is very high. The housing of the integrated soil nutrient sensor is sealed with epoxy resin vacuum, completely waterproof, with IP68 protection class. It can be used outdoors for a long time. It is resistant to electrolysis and corrosion.Power Supply : 12 - 24V DCOutput Signal : RS485Protection level : IP68Temperature measuring range : -45-115Moisture measuring range : 0-100%RHPH measuring range : 3-9PHNPK measuring range : 0-1999mg/kgEC measuring range : 0-10000us/cmTemperature Precision : 0.5Moisture precision : 3% in 0-53% range ; 5% in 53-100% range
