Ever needed a microphone for your project. This tiny little board will fulfill all your needs - it is not only mobile, but as well easy to connect. A low power, efficient, omnidirectional AMP401 microphone has an analog output. It works great for near and long range uses and is particularly suitable for a mobile projects given its extremely low energy consumption. You can use it in a range of applications - we can see it used in smartphones, cameras or electronic nannies.
Sensors enable us to receive signals from the outside world. Technically, sensors are objects capable of receiving a signal, and when this signal reaches the predefined level of sensitivity of the sensor, they are able to send information to the rest of the circuit. Sensors are often used in robotics, as they enable robots to communicate with their environment, be it by vision (light and colour sensor), hearing (sound sensor) or smell (gas sensor). We offer a wide variety of sensors for all applications and price ranges.

The optical module sensor (reflective) with comparator LM393, which detects obstacles with high precision.
The ideal obstacle detection detector for the installation of smart robots.
TCRT5000 - reflective optical sensor that has a compact construction where the light emitter and receiver are placed in the same direction to detect the presence of a object using infrared reflection on the object.
The working wavelength is 950nm.
The transmitter is infrared LED and the phototransistor receiver.
By using LM393 comparator the module has a binary output (D0) that is at level 1 (object is detected).
The sensor allows the detection of an object at a distance of up to 12 mm.

DFRobot Gravity: The V2 analogue pH meter is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. The DFRobot ph sensor is commonly used in various applications such as aquaponics, aquaculture and environmental water testing.
The pH is a value that measures acidity or alkalinity.
GamePad for micro:bit V4.0 adopts a high-precision three-axis analog quantity joystick. The combination of joystick and gamepad allows you to control the direction and speed of Maqueen at the same time. In addition, there are 7 programmable buttons, which means you can explore more interesting functions and more flexible controls. In the latest V4.0 product, we have placed the external battery box on the PCB, which is more convenient to use.
