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.

A Whadda Universal Temperature Sensor Mounting Kit, used for measuring indoor and outdoor temperatures, controlling the rise/fall of temperature in homes, equipment, control of temperatures in some processes, visualization of the temperature on your website, control of the temperature of your pool, etc.

An Educational Kit with Arduino and about 30 Modules and Components, ideal for an introduction to electronics.

A Starter Kit Educational DIY Smart Home with the Arduino UNO R3, in a Component Box with a Protective Cover, with a Sensor of PIR Movements, a Bluetooth V4.0 Module, a Water Sensor, a Relay Module, a Humidity Sensor, an LCD1602 Display, even a Screwdriver, a Set that in total consists of about 110 pieces.

This Disk Load Cell (sometimes called the Strain Gauge) can translate up to 200kg of Pressure(Force) into a Electrical Signal. Each Load Cell is capable of measuring the electrical resistance that changes in response and proportional to the voltage (eg pressure or force) applied to the disk. With this gauge, you'll be able to tell how heavy an object is, if an object's weight changes over time, or if you simply need to feel the presence of an object by measuring the tension or load applied to a surface.

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.

Electrolytic Condenser for use in rectifier circuits, power supplies and general electronic circuits. When connecting the Electrolytic Condenser, check the polarity of the terminals to prevent component damage. The larger terminal corresponds to the positive, and the smallest to the negative.

This Module is a Rotary Incremental Encoder. It encodes the shaft rotation signal and outputs the signal by electronic pulse. The Grove –Encoder is a module of the Grove series and has a standard Grove interface. When you need to add a knob to your project, for example a volume knob for a speaker, a selection panel or a digital input, this should be your first choice.

The HC-12 433MHz Transceiver is a wireless communication Module, which is based on the RF SI4463 chip, has a built-in microcontroller and can be configured by AT commands, the maximum output power is 100mW (20dBm) and the receiver sensitivity differs from: 117dBm to -100dBm, depending on the transmission speed. Accepts 3.2V - 5.5V and can be used with 3.3V and 5V UART voltage devices.

A Module with GPRS Antenna, operation Wireless and SIM Card.

TOSR02-T - USB / Wireless 5V 2-channel Relay Module Support for temperature sensor

The ESP32-CAM is a WIFI + Bluetooth Development Card based on the ESP32 Chip, with the additional possibility of using a camera. It is ideal for a variety of loT applications.

The Kit Set of Torix Connectors is widely used in building wiring. By selecting the best insulation material, it is durable, corrosion free, anti-aging, pressure 4kv and against electric shock. It breaks the disadvantage of the traditional wiring method which is problematic in wiring, easy to leak, and easy to corrode.

Now the ESP8266 D1 Mini v3 is no longer alone! If you like WiFi communication, especially with ESP8266 chips, you can't miss this kit that includes several modules such as sensors, button, LED, Display, Relay, protoboard, among others. And you couldn't miss the respective ESP8266 D1 Mini v3 to be able to program in an Arduino environment and develop your wireless and IoT projects.

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 ESP8285 ESP M2 Module provides easy-to-use WiFi for any UART port and is compatible with the HC-06 Bluetooth modules. If your project uses Bluetooth, it is very easy to convert it to WiFi. Using the integrated web interface, WIFI-UART communication can be configured for TCP or UDP sockets on any port.

Grove's capacitive humidity sensor (corrosion resistant) is a soil moisture sensor based on changes in capacitance. Compared to resistive sensors, capacitive sensors do not require direct exposure of metal electrodes, which can significantly reduce electrode erosion.

This is a small Force Sensitive Resistor . It has an Active Detection Area of 0.16 "(4mm) in Diameter. This FSR from Interlink Electronics varies its Resistance depending on how much Pressure is being applied to the Detection Area. The stronger the Force, the lower the Resistance. When there is no Pressure Applied to the FSR, its Resistance will be greater than 1MΩ, with the Total Pressure applied to the Resistance it will be 2.5kΩ Two Pins extend from the Bottom of the Sensor, making it friendly to the Breadboard. are simple to set up and great for detecting pressure.
