Follow Guided Projects Materials: Use digital tutorial materials, datasheets, wiring diagrams and example code for compatible UNO R3, MEGA 2560 and Nano boards, then adjust thresholds, timing and logic to create custom experiments
This sensor kit comes with 37 basic sensors and modules, which is good for learning basic knowledge about sensors. The main controller is Not Included.
It comes with detailed tutorials which include pictures and code and 37 projects, explained step by step. Note we provide arduino tutorials, without Raspberry Pi tutorials.
Each module has 3-4 pins broken out that make it easy to plug into a solderless breadboard or hook up to with Dupont wires. They are intended to be used with the Arduino platform, but can also be used with the Raspberry Pi platform.
Packed well in a nice box, also each item packed well separately.
The LD2410C is a high-performance 24GHz human presence detection module that employs FMCW (Frequency-Modulated Continuous Wave) technology to precisely identify human targets within a predefined area
By combining radar signal analysis with sophisticated human recognition algorithms, it achieves high-accuracy presence tracking while simultaneously measuring target distance and supplementary metrics
In contrast to traditional sensors, the LD2410C is capable of detecting not only moving persons but also stationary individuals, subtle movements, and seated or reclining postures, delivering enhanced detection reliability
Offering real-time monitoring and rapid response, the module covers a detection range of up to 5 meters with a distance resolution of 0.75 meters, guaranteeing consistent operation
Ultra-Thin & Responsive: The RP-C Pressure Sensor is a cutting-edge force sensitive resistor that offers rapid response times under 10ms. With a slim profile of just 0.4mm, this thin film pressure sensor is perfect for Arduino projects and other applications requiring precise pressure measurements within a 20g to 2kg range.
High Durability & Sensitivity: Engineered for over a million uses, the RP-C force sensor ensures consistent performance with less than 3% variance in resistance. Its high sensitivity triggers at a mere 20g of force, making it an ideal pressure sensor for Arduino enthusiasts and professionals alike.
Flexible & Versatile: This force sensor’s flexible design and static or dynamic pressure modes make it versatile for a wide range of applications. Whether for industrial use or DIY projects, the RP-C adapts to both static and dynamic pressures up to 10Hz frequency.
Stable & Reliable: With a default resistance threshold of less than 200kΩ for activation, the RP-C pressure sensor provides a stable and reliable performance. It operates flawlessly within a temperature range of -40°C to +85°C, ensuring durability and precision in various environments.
Adopting a slot type photoelectric sensor, it consists of an infrared light-emitting diode and an NPN photoelectric transistor, with a slot width of 5.9mm.
As long as a non-transparent object passes through the slot, it can trigger to output a low TTL level.
Using Schmidt trigger to jitter pulses is very stable and can be used for small car speed measurement, distance measurement, and other applications!
