Soil Hygrometer Detection for arduino

Description

About this item:

Key Features:

• Sensor Type: Capacitive (recommended) / Resistive
• Measurement Principle: Measures soil dielectric permittivity (capacitive) or electrical resistance (resistive)
• Operating Voltage: 3.3 V – 5 V DC
• Output Signal: Analog voltage proportional to soil moisture (0 to Vcc)
• Output Voltage Range: ~0.5 V (wet) to ~4.5 V (dry) (varies by sensor & soil)
• Current Consumption: < 10 mA
• Input Impedance: High (>1 MΩ for capacitive sensor)
• Arduino ADC Resolution: 10-bit (0–1023)
• Typical ADC Values (Dry Soil): 700 – 1023
• Typical ADC Values (Wet Soil): 300 – 400
• Accuracy: ±5-10% (after calibration)
• Response Time: < 1 second
• Operating Temperature: -10°C to +60°C
• Storage Temperature: -20°C to +70°C
• Humidity Resistance: Waterproof probe (capacitive sensor)
• Probe Material: Plastic encapsulated (capacitive), metal electrodes (resistive)
• Probe Length: ~7 cm
• Arduino Interface Pins: VCC (3.3/5V), GND, Analog Out (A0)
• Calibration Procedure: Measure ADC at dry and saturated soil, map sensor reading linearly
• Power Consumption: < 10 mA
