Soil Moisture Sensor

The DO output interface can be directly connected to a micro-controller IO port, if there is a block detection sensor, such as the speed of the motor encoder can detect. DO modules can be connected to the relay, limit switch, and other functions, it can also with the active buzzer module, compose alarm.

The Obstacle Detector sensor module is perfectly adaptable to the environment light, IR Object Avoidance Sensor has a pair of infrared transmitting and receiving tubes; transmitting tube emits infrared in a certain frequency, when detecting direction meets with obstacles(reflecting surface), reflected infrared will be received by the receiving tube; after the comparator circuit processing, the green indicator will light up, at the same time signal output interface to output digital signal(1 low-level signal). Users can adjust the detection distance through the potentiometer knob, effective distance range 2~30cm and working voltage is 3.3V to 5V. The Obstacle Avoidance module LM393 can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, black and white line tracking, and so on many occasions.

The TCRT5000 and TCRT5000L are reflective sensors which include an infrared emitter and phototransistor in aleaded package which blocks visible light. The package includes two mounting clips. TCRT5000L is the long lead version.

Mounting Bracket Holder Stand is specifically designed for the HC-SR04 Ultrasonic Sensor Module. With this ultrasonic sensor you can attach the le to your application such as small robots or DIY projects very quickly and conveniently. This best mount bracket is made from good quality Acrylic. This mounting holder has mounting holes of a diameter of 3.8mm. Use this Arduino distance measuring sensor to easily attach your ultrasonic distance sensor to your robots, onto a servo for panning, and anywhere else you’d like. 90 degree mounting with 3 screw holes at the base and 4 screw holes for the ultrasonic sensor itself.
