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.
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.
An Educational Kit with Arduino and about 30 Modules and Components, ideal for an introduction to electronics.
XBee 6.3mW Wire Antenna - Series 2C ZigBee Mesh
MP3 Player Shield - SparkFun
The 8 Environment Sensors Kit, M5Stack Env Kit, includes the 8 Earth, Angle, Pir, Hub, Light, Rgb, Ir and Env Sensors.
A Module with GPRS Antenna, operation Wireless and SIM Card.
Can be used to monitor the heart rate of the patient and athlete. The result can be displayed on a screen via the serial port and can be saved for analysis.
LinkIt Smart 7688 Duo - Arduino to Linux
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.
When you assign a high level to the module pin, the electro magnet can suck magnetically conductive objects. Otherwise, it will release the object.
An electro magnet is a type of magnet in which the magnetic field is produced by electric current. An electric current flowing in a wire creates a magnetic field around the wire, due to the Ampere Law. To focus the magnetic field on an electro magnet, the wire is wound into a coil with many twists of wire side by side. The Magnetic Field of All Twists of the Wire passes through the Coil Center, creating a Strong Magnetic Field there.
It's Easy to Use to Learn the Electro Magnet Principle.
Kit Thermostat with LED Indicator - Velleman.
This Load Sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales. This sensor can measure up to about 110 pounds.
