Soil Moisture Sensor and Soil Detector Module Soil Moisture Test Soil Moisture Test Corrosion Resistance Probe for Arduino
NPR 750.00This module is a soil moisture detector sensor module + it has corrosion resistance probe which are compatible with the Arduino. This soil moisture sensor can read the amount of the moisture present in the surrounding soil.This soil moisture arduino compatible sensor uses the two probe to pass the current through the soil, as if in the soil more water is present than that soil will conduct the electricity more easily like less resistance will be offered and if the soil is dry than that soil will offer more resistance and soil conduct electricity will be poor. This Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help. They can be very to use, just insert it into the soil and then read it. With help of this sensor, it will be realizable to make the plant remind you. if there is requirement of water or not. This module requires input supply voltage of 3.3 – 5VDC and its working current is less than 20mA. This soil humidity detection module includes a potentiometer and soil moisture thresholds.

JSN-SR40T Ultrasonic Ranging Sensor Module
NPR 1,800.00Using IO port trig trigger location, to the high level signal of at least 10us module automatically sends 8 40khz fang bo, automatic detecting whether a signal return. A signal return, a high level is output through the io port echo, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340m/s)) /2ranging, the measured object area of not less than 0. 5 square meters and the plane as required to smooth, otherwise affect the measurement results.
