Outdoor Soil Moisture Temperature Sensor ES101SM Soil temperature affects plant growth indirectly by affecting water and nutrient uptake as well as root growth. At a constant moisture content, a decrease in temperature results in a decrease in water and nutrient uptake. At low temperatures, transport from the root to the shoot and vice versa is reduced. Therefore a real-time data of soil temperature and moisture is vital for soil management. ES101SM sends measured data through Modbus RS485 output to IoT gateway, and IoT gateway collects all sensor data to the cloud platform for real-time information. Optional IoT Router and Cloud Platform - ThingsMaster – – – Support Modbus to connect optional NBIoT Gateway WR222 for one or many sensors Real-time online monitoring, analysis, reporting Remote cloud security and visual management Moisture measurement range: Temperature measurement range： -40℃~80℃ Signal output RS485 2-Wire output (Modbus protocol) Working voltage Maximum power consumption Work environment Physical parameters 45*15*123mm, Probe length: 70 mm Probe material: Anti-corrosion special electrode Sealing material: Epoxy resin (black flame retardant) Cable length: standard 2 meters (Can be customized) Protection class: IP68 Register Address Range：0~100% ; Real Value = (Read Data /10) Range：-40℃~80℃ ; Real Value = (Read Data /10) Baud Rate Model Name Outdoor Soil Moisture and Soil Temperature, 40~80°C, 0~100%RH, 70mm Probe, RS485 Modbus, 10-30V Power Package List 1 x Product Unit, 1 x Quick Installati

Outdoor Soil pH sensor ES101SPH Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient availability by controlling the chemical forms of the different nutrients and influencing the chemical reactions they undergo. The optimum pH range for most plants is between 5.5 and 7.5; however, many plants have adapted to thrive at pH values outside this range. The SPH sensor gives you real-time data by the connectivity of gateway and cloud platform. Optional IoT Router and Cloud Platform - ThingsMaster – – – Support Modbus to connect...

Outdoor Soil EC and Moisture Sensor ES101SEC Soil electrical conductivity (EC) sensor measures of the amount of salts in soil (salinity of soil). It is an important indicator of soil health. Soils containing excess salts occur naturally in arid and semiarid climates. The salinity of the soil, irrigation water or fertilizer solution is an important parameter affecting the root zone. Any of these factors can have a significant effect on plant growth and quality. The presence of high salt levels indicate adjustments are required. Low-salt levels could also lead to nutrient deficiencies. The SEC...
