➤➤ This is a simple moisture sensor that can detect the soil moisture. When the soil is close to water, the module outputs a high level and vice versa. Use this sensor to create an automatic irrigation device that cannot manage plants in your garden.
➤➤ ➤ Sensitivity is adjustable (blue digital potentiometer setting in the picture)
➤ ➤ The module has a dual output mode, the digital output is simple and the analog output is more accurate.
➤ ➤ Fixed screw holes for easy installation power indicator (red) and digital switch output display (green). The comparator uses the LM393 chip and works stably. Examples of use1.
➤ ➤ Motor DC motor Since this module is a 2-way H bridge plate, it is possible to drive two motors at the same time. After ENB allows ENA, the PWM signal input of IN1 IN2 can be used to control the speed and direction of motor 1. The PWM signal can be input via IN3 IN4 to control the speed and direction of motor 2.
