Temperature sensing module using an NTC thermistor. The output signal at ‘DO’ switches high when the preset (adjustable) temperature is reached. An analog output signal from the sensor is available at pin ‘AO’
Use this module to detect a magnetic field. This is an Analog sensor, when a magnet is detected the LED will turn on, otherwise the LED will be off.
Pulse sensor Pulse Heart Rate Sensor Module
With the sound module, we can detect the presence of loud sounds. While this module has a microphone on it, our Arduino does not have the brains to interpret or record the audio directly (there are some shields you can get that will do this).
It's a push button!
Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple.
Arduino to SD card interface module.Use this to read and write to the SD card using your arduino.
Do you love your plants? Do you want the best for them? Or are you more like me and forget they are there until your mother is about to come over then rush round the house making sure they have been watered? Either way this kit is for you!
This is a 10 pack of Biomedical Sensor Pads, disposable electrodes that can be used to measure EEG, ECG and EMG levels. these little pads are perfect for short-term monitoring of Neurofeedback and Biofeedback purposes. They are to be used once and are very handy because of int...
Gravity: Digital Signal Isolator is capable of isolating I2C digital signal and providing isolated power to the sensor module, effectively preventing mutual interference between the sensor modules. This digital signal isolator can be used for multi-parameter water quality dete...
DFRobot Gravity: Analog pH meter V2 is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. It is commonly used in various applications such as aquaponics, aquaculture, and environmental water testing.
DFRobot's latest generation of digital DHT11 Temperature and Humidity sensor is as powerful as it used to be but easier to use.
When wired with a 5v supply, the power light will be on.
45 sensors for Arduino
This Light Dependant Resistor (LDR) can be used to easily measure ambient light with your Arduino or other board with analog input. You will need to set this up as a voltage divider with a resistor of around 10KΩ.
CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ.
This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus. This...
The Prop Shield with Motion Sensors for Teensy 3.2 and Teensy-LC is meant for making interactive light and sound effects on small handheld props and wearable costumes! Good for all sorts of projects, and designed by the creator of the Teensy so you know it's gonna be well supp...
This is a touch sensor for Arduino. This sensor is a toggle output type: touch-on then touch-off.
This small (14mm diameter) piezo element is nicely enclosed so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts AND you can use it as a sensor, to detect fast ...
We designed this board to give the user a very discrete button without any sharp edges. Button closes when you push it and opens when you release (momentary push button).
This white LED light module has a shiny white color. It is ideal for Arduino starter. This module can be easy to be plugged on IO/Sensor expansion shield.
A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force.Micro switches are very widely used; among their applications are appliances, machinery, industrial controls, vehicles,...
The RHT03 (also known by DHT-22) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature.
These simple switches are the Mechanical Bumper sensor for the SparkFun RedBot, giving you the ability to detect a collision before it really happens. This sensor works by acting as a SPST switch. When the “whisker” bumps into a foreign object it will make contact with a nut n...
The MPU-6050 sensor contains a MEMS accelerometer and a MEMS gyro in a single chip. It is very accurate, since it contains 16-bits analog to digital conversion hardware for each channel. Therefor it captures the x, y, and z channel at the same time.
The DS1307 Real Time Clock module developed by one of our designers: Waiman. The module comes fully assembled and pre-programmed with the current time (ok, so it's our current time - MST). The included Lithium coin cell battery (CR1225 41mAh) will run the module for a minimu...
This is the same temperature sensor that is included in our SparkFun Inventor’s Kit. The TMP36 is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. It also doesn’t require any external...
