The hall effect 3144 is a digital output hall sensor
The hall effect 3144 is an integrated Hall effect non-latching sensor
It will return a higher value around 5
ESP8266 has powerful onboard processing and storage capabilities allowing it to integrate with sensors and other devices through GPIOs with minimal development up-front and minimal loading during runtime
Soil Moisture Sensor Digital The hall effect 3144 isIntroduction: The fork shaped probe with two exposed conductors, acts as a variable resistor (just like a potentiometer) whose resistance varies according to the water content in the soil. This resistance is inversely proportional to the soil moisture: The more water in the soil means better conductivity and will result in a lower resistance. The less water in the soil means poor conductivity and will result in a higher resistance. The sensor produces
