Arduino temperature sensor1/2/2023 ![]() The perfect sensor for receiving button presses from an infrared remote control. Infrared IR sensor module (KY-022) for use in infrared data transmission projects. Great for controlling lamps or other appliances with an Arduino. The KY-019 5V one channel relay module allows you to control high-voltage/high-current devices using a low-voltage digital output pin on the Arduino. The trigger value can be adjusted based on the position of an on-board potentiometer. This sensor triggers a digital output based on the intensity of the sound. This is the KY-037 sensor is a highly sensitive module for picking up sound and audio. The KY-039 heartbeat detects heartbeat/pulse via the finger using a photoresistor and flashing an LED. The KY-026 IR Flame sensor module is sensitive the IR light spectrum emitted by open flames and triggers a digital output. You can see this in our Ardiuno Railroad Crossing project. This active piezo-buzzer module KY-012 will make a beep sound (2.5 Khz) when 3.3V is applied to its input pins. In most cases these sensors will also work with the Raspberry Pi without modification. For example, in lieu of the two-color LED module, you could use a two color LED, 330 Ohm resistors, and a breadboard wire separately to create your own Arduino module. While this makes creating with your Arduino simple, its not entirely necessary. This means they already include things like current-limiting resistors, terminal posts, and potentiometers on-board to help you save time. This list of Arduino sensors and modules are in “module” form-factor. ![]() Since modules and sensor grow on the same trees, we’ve made it easy for you to find everything you need for your Arduino projects in one place. Modules could be LCD character displays, LED dots displays, transistor modules, and the like. List of Arduino Sensors and ModulesĪlthough modules are not expressly sensors we’re including them in the list here along with the sensors. In this list of Arduino sensors we’ll explain what each one is used for and some quick links to where you can purchase them. There are many, many sensors and the differences and uses of some of them can be very confusing. The readings are much smoother and an odd failed to read a month which I filter out.Due to many requests by our user community I’ve put together this handy list of Arduino sensors and modules. I found that it worked better on the 3.3 volt pin. The readings also oscillated a few points.Īfter experimenting after reading some comments about RF interference etc. I originally used 5volt pin on Arduino and I did find I got some failed to reads now and again usually during very cold nights. I doubled up two of the eight available wires for each line. I did find that joints need a good solder connection and all screened. This has been running stable readings for over 6 months now. I upload my readings to Cayenne cloud based server with apps to view readings every 3 minutes. The Arduino is inside and the cable runs into the greenhouse about 5 metres of cable then carries on to a place on the fence at the end of the garden that is always in the shade to get an accurate shade temp reading. I have two waterproof ds1820 sensors running over cat 6 cable.
