Uses the NTC Thermistor Sensor, Good Sensitivity. The Clean Waveform of the Comparator Output Signal is Good, Driving Capacity.
The KY039 Infrared Pulsation Sensor is a small, inexpensive plate used to measure the electrical activity of the heart to enable heart rate / pulse checking in different parts of the human body. The data presented by the Sensor is useful for formulating exercise routines or even for studying and verifying heart activity levels.
LDR Light Sensor with Relay
An Educational Kit with Arduino and about 30 Modules and Components, ideal for an introduction to electronics.
The imported PL2303HX controller can stabilize the flash at high speed. With a 500mA auto-recovery fuse for protection and two data transmission indicators that can monitor the data transfer status in real time. The entire board is coated with a high-quality transparent heat-shrinkable layer, rendering the PCB in a state of isolation from the outside, so that the board is not burned. Electrostatic package, ensures that the plate will not be damaged before use. Supports WIN7 system.
This Module of Switch Reed uses a Small Device called a Leaf Switch. When the Device is Exposed to a Magnetic Field, the Two Ferrous Materials within the Switch are joined together and the Switch closes. When the Magnetic Field is Removed, the Switch Opens.
The Arduino WTV020-SD MP3 Module is a voice recording module with 1GB SD Card storage capacity. You can upload WAV and AD4 format files that conform to FAT formatting. It supports 6KHz to 32KHz, being 36KHz for AD4 files and 6-16KHz for voice sampling rate (Audio Sampling).
The Sensor of Image Charmed Labs Pixy 2 CMUcam5 is smaller, faster and more capable than the original Pixy. Like its predecessor, Pixy2 can learn to detect objects, just by pressing a button. In addition, Pixy2 has new algorithms that detect and track lines for use with line following robots. The new algorithms can also detect intersections and "traffic signs". Traffic signs can tell your robot what to do, such as turning left, turning right, slowing down, etc.
The Rotary Encoders are similar to Potentiometers, however, as they have no physical limits, they can run indefinitely. However, the similarity to a potentiometer is only physical, instead of having a variable resistance, in this type of Encoder we have an impulse output with 20 impulses per turn. In addition to the impulse output, it also has a push button function with two dedicated pins that close when we press the Encoder shaft.
This ENC28J60 RJ45 Ethernet Shield is ideal for enabling your Arduino Nano with an Internet connection.
The motor shield is based on the L298 , it is a double complete bridge driver designed to drive inductive loads, such as relays, solenoids, DC and stepper motors.
Solid State Relay - 8 Channels
This Voice Recognition Module with Microphone for Arduino can recognize up to 15 voice instructions and be suitable for most cases involving voice control. With this module, we can control cars or other electrical devices by voice.
A Module with GPRS Antenna, operation Wireless and SIM Card.
