2. Ardest


Ardest High Sensitivity Water Sensor Module for Arduino Water Level Meter Wet Gauge Moisture Checking of Tank Dog Bowl Refilling Device

Ardest #ad - It measures about 1-5/8" long x about 7/8" wide. Works great! zero output when dry. The overall dimension of the the sensor is about 2-3/8" long including the active circuitry part near the connector.

Works perfectly fine for my uses, trip relay for pump and backup audio alarm for overflow. Good analog sensor, stable. Water level/height Depth Detection Sensor Module for Arduino. Very good at water & moisture. This sensor works well to detect the presence of water. Able to detect even one drop of water + detects water level as expected. Very nice. The sensor part is the rectangular part without circuit components. Works perfectly with arduino. Good for simple applications. A quick test in a glass full of water gave consistent readings from 500 - 720 ish.

5. Yoochin


Yoochin 5pack/lot Soil Moisture Hygrometer Detection Humidity Sensor Module for arduino Development Board DIY Robot Smart Car

Yoochin #ad - 2 module in the soil humidity less than a set threshold value when the DO port output high, when the when soil humidity exceeds the threshold value is set, the module D0 output low;. Soil the hygrometer detection module robot intelligent car soil moisture sensor for arduino.

1 vcc external 3. 3v-5v 2 gnd external gnd 3 do small board digital output interface 0 and 1 4 AO the small plates analog output interface. Usually you can get the products in 16-32 days. Lead time: 1-4 days, shipping time: 14-28 days. Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil. 3 small plates digital outputs d0 can be directly connected with the microcontroller, and which can form a soil moisture alarm equipment; 5 small plates analog output AO and AD module connected through the AD converter, microcontroller to detect high and low, and thus to detect soil moisture; 4 small plates digital output DO shop relay module can directly drive the buzzer module, you can get more accurate values of soil moisture;.
