The Color sensor module base on TCS230 which is a programmable color light-to-frequency converter, it could filter RGB data from source light and convert it to a square wave(50% duty cycle) with frequency directly proportional to light intensity (irradiance).
Put on your sunglasses before using this matrix with 64 eye-blistering RGB LEDs adorn the panel for a blast of configurable color. Arranged in a 8x8 matrix, each pixel is individually addressable. Only one pin is required to control all the LEDs. You can cut a trace and use nearly any other pin if you need some customization.
The UV Sensor is used for detecting the intensity of incident ultraviolet(UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation. This module is based on the sensor UVM-30A, which has a wide spectral range of 200nm-370nm. The module outputs electrical signal which varies with the UV intensity, which gives your...
With compact design, the board can integrate the real-time clock module DS1307, EEPROM memory AT24C32 and digital temperature sensor DS18B20 (not supplied on the board) which are connected via I2C bus together on a 27mm*28mm*8.4mm board.
“An open-source firmware and development kit that helps you to prototype your IOT product within a few Lua script lines” Based on ESP8266 ESP12E wifi board, on-board USB-TTL support directly flashing from USB port, also on-board power circuits and all IOs setup.
DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. Compared to the DS1302 solution, the DS3231 has many advantages, it function with a VCC ranging from 2.3V to 5.5V and has a battery backup. Unlike
It's a small USB to TTL serial tool, using the PL2303 chip.
You can use it to connect some serial device to your PC via USB port, an avr, an msp430 or an stm32 for example.
It's very cheap compared to the ft232 alternative and works very well, up to more than 1mbit/s.
