M1 AI+lOT Module K210 Deep learning
AI chip normally refers to ASIC chip that aims at AI algorithms. Although the conventional CPU and GPU can be used to execute AI algorithms, they have been greatly limited in their speed, performance, and practicality. Compared with traditional processor chip, AI chip offers faster speed, more co...
Ring Inductive Proximity Sensor (22mm Hole Diameter)
This inductive ring proximity sensor detects metal objects as they enter or pass through a 22 mm ring opening. Operating on a 6–36 V supply with NPN normally-open output, it delivers a sub-1 ms response time — fast enough to reliably detect small, fast-moving metal parts. The sensor features an ...
Megapixel 720p USB Wide-angle Camera for Raspberry Pi and NVIDIA Jetson Nano
A compact 720p USB camera module with a 140-degree wide-angle lens. Using the standard UVC protocol, it's plug-and-play on Raspberry Pi, NVIDIA Jetson Nano, and any system supporting USB Video Class — no driver installation required. The compact 38 × 38mm form factor makes it easy to embed in en...
FS-600 Geiger Nuclear Radiation Detector
FS-600 is a small height radiation detector. Its main function is to monitor X-ray, ♥-ray and ⑤-ray. The detector of this instrument is an energy compensation Geiger counter (hereinafter referred to as tube). It is characterized by accurate measurement and high range. This product adopts 32-bi...
IR Flame Sensor Module
This IR flame sensor module detects flames and infrared light sources in the 760–1,100 nm wavelength range. With a detection angle of approximately 60° and a test range of up to 80 cm (depending on flame size), it provides both digital and analogue output for flexible integration with Arduino, Ra...
SDM15 ToF Single-Point Ranging LiDAR Sensor (15m, UART, Supporting ROS & ROS2)
The laser transmitter emits laser light at time t1. The laser collector collects the reflected laser distance at time t2 = (t2-t1)*light speed/2, because t2-t1 is the round-trip time from laser emission to reception.SDM15 distance of 15 meters, making it capable of laser ranging in most indoor sc...
Adafruit STEMMA Reflective Photo Interrupt Sensor - TCRT1000
·
The Adafruit STEMMA Reflective Photo Interrupt Sensor uses a TCRT1000 right-angle optical module to detect reflective surfaces. An onboard IR LED emits light, and when an object reflects it back to the IR phototransistor, the output pin drops from high toward 0V — making it easy to detect the pre...
Adafruit ADG728 1-to-8 Analog Matrix Switch
·
The Adafruit ADG728 is a solid-state 1-to-8 analog matrix switch controlled over I2C. Unlike relays, analog switches have no moving parts, won't wear out, and switch in approximately 100 ns. Use it to route up to 8 analog signals (up to 5V) to a single common pin, or vice versa — the signal path ...
Adafruit ADG729 Dual 1-to-4 Analog Matrix Switch
·
The Adafruit ADG729 is a solid-state dual 1-to-4 analog matrix switch controlled over I2C. It provides two independent groups of 4 switches — four channels routed to the DA pin and four channels routed to the DB pin — giving you 8 total switches in a compact package. Unlike relays, analog switche...
