📄️ MQ2 Sensor

MQ2 analog gas sensor is used in gas leak detection equipment for consumer and industrial markets, suitable for detecting LPG, isobutane, propane, methane, alcohol, hydrogen, and flue gas, with high sensitivity and fast response time. The sensitivity can be adjusted by a potentiometer.

📄️ Crash sensor

The crash sensor is a sensor module based on collision elements, with simple circuit design and high sensitivity.

📄️ Rainbow LED

Octopus RGB Rainbow LED is a single rainbow LED electronic building block of our OCTOPUS series. Its basic design is based on the OCTOPUS electronic building block series. Its appearance, PCB fixing holes, and electronic building block interface settings are the same. The onboard LED is an intelligent external control LED that integrates the control circuit and light-emitting circuit. It has the advantages of low voltage drive, high brightness, and large scattering angle.

📄️ Light Sensors

Light sensors are sensors that can detect light intensity. They are small, inexpensive, low power, easy to use, and do not wear out.

📄️ DHT11 Temperature and Humidity Sensor

The temperature and humidity sensor is a device used to measure and monitor the temperature and humidity in the environment. It can provide accurate temperature and humidity data to help people understand and control environmental conditions. This sensor is widely used in many fields, including meteorological observation, indoor environment monitoring, agriculture, warehouse management and automatic control systems.

📄️ Water level sensor

Octopus Water level sensor is our OCTOPUS series of water level sensor electronic building blocks. Its basic design is set according to the OCTOPUS electronic building block series. Its appearance, PCB fixing holes, and electronic building block interface settings are the same.

📄️ Water Level Sensor

3V relay is an electrical switch that can open or close a circuit by controlling the current. It consists of an electromagnetic coil and a set of switch contacts. When current passes through the electromagnetic coil, it generates a magnetic field, which attracts or pushes the contacts, thereby opening or closing the circuit.

📄️ Fan Module

OCTOPUS Motor Brick is a simple electronic building block fan motor driver module

📄️ 180°Servo

A servo motor is often called a servo. It is a small device with an output shaft. When we send a control signal to the servo, the output shaft can be rotated to a specific position. As long as the control signal remains unchanged, the servo mechanism will keep the angular position of the shaft unchanged. If the control signal changes, the position of the output shaft will also change accordingly. In daily life, servos are often used in remote control aircraft, remote control cars, robots and other fields.

📄️ 3V Water Pump

The 3V water pump is a small, compact water pump that is commonly used in water treatment systems in homes, industry and agriculture.
