This sensor is essentially a reed switch, encased in an ABS plastic shell. Normally the reed is 'open' (no connection between the two wires). The other half is a magnet. When the magnet is less than 13mm (0.5") away, the reed switch closes. They're often used to detect when a ...

DF-SEN0019

This is an Arduino infrared distance sensor. It has an adjustable detection range, 3cm - 80cm. It is small, easy to use, assemble, and inexpensive.

Overview

DF-SEN0014

The Sharp distance sensors are a popular choice for many projects that require accurate distance measurements. This IR sensor is more economical than sonar rangefinders, yet it provides much better performance than other IR alternatives. Interfacing to most microcontrollers is...

SF-SEN-00639

This is the fantastically easy to use sensor from Maxbotix. We are extremely pleased with the size, quality, and ease of use of this little range finder. The serial interface is a bit odd (it’s RS232 instead of standard TTL), but the PWM and Analog interfaces will allow any mi...

SF-SEN-13959

This is the HC-SR04 ultrasonic ranging sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.

DF-KIT0020

An Ultrasonic sensor with scan capability is a must have feature for most robot application. This Ultrasonic scanner kit provides a cost effective way to have such feature for your robot application. This kit is able to scan upto 120 degree area with 10-400 cm (3.94-157.48") d...

DF-SEN0005

This low cost SFR02 ultrasonic ranger has both I2C and Serial interfaces. New AutoTune algorithms intelligently back the minimum range right up to the transducer ringdown for the very best performance possible, automatically, in the background, and with no calibration cycles n...

AF-3316

The VL6180X (sometimes called the VL6180) is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny laser source, and a matching sensor. The VL6180X can detect the "time of flight", or how long the laser light has taken to bounce back to th...

DF-SEN0013

This SHARP infrared distance sensor takes a continuous distance reading and returns a corresponding analog voltage with a range of 20cm (8") to 150cm (60").It can be usually applied as obstacle avoidance and path planning sensor.

AF-3317

The VL53L0X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source, and a matching sensor. The VL53L0X can detect the "time of flight", or how long the light has taken to bounce back to the sensor. Since it uses a ...

DF-SEN0164

This adjustable infrared sensor features a high-sensitivity photoreflector to perform distance detection function,ranging from 3cm to 50cm. When the infrared light emitted by the emitter gets reflected on a surface that blocked it, the phototransistor can pick up the signal fo...

Overview

AF-158

Hall effect sensors detect whether a magnet is near. Useful for non-contact/waterproof type switches, position sensors, rotary/shaft encoders. I tried dozens of different hall effect sensors to see which one would work best for the SpokePOV kit (to determine the wheel location...

DF-SEN0002

The URM04 Ultrasonic sensor is developed based upon our popular URM37 ultrasonic sensor, it is using RS485 interface which allows multiple sensors to be used simultaneously . The RS485 interface allows a number of sensors working together. Up to 32 URM04 may be connected toget...

DF-SEN0042

This is an edge detection sensor from DFRobot. It will help your robot detect the edge of a precipice, preventing it from falling off a table or down the stairs to it's certain demise! This IR distance sensor is connected to an arduino digital pin.

DF-SEN0081

The XL-MaxSonar-WR sensor provides very short to long-range detection and ranging, in a compact, robust PVC housing, designed to meet IP67 water intrusion, and matches standard electrical 3/4" PCV pipe fittings. The sensor puts 1/2 watt of peak power into the efficient transf...
