The module (MicroSD Card Adapter) is a Micro SD card reader module, through the file system and the SPI interface driver, MCU to complete the file system to read and write MicroSD card. Arduino users can directly use the Arduino IDE comes with an SD card to complete the library card initialization and read-write. -
Highlights: By adjusting the potentiometer can set the length of time. MicroUSB 5.0V power supply with an input port, easy to use. 5 ~ 30V wide supply voltage. External signaltrigger and keytriggerin two ways. With a relay indicator. Anti-interference ability, the relay at various interference will not misoperation, suitable for industrial control. -
This module allows you to detect when sound has exceeded a set point you select. Sound is detected via a microphone and fed into an LM393 op amp. The sound level set point is adjusted via an on board potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low. -
This module integrates DHT11 sensor and other required components on a small PCB. The DHT11 sensor includes a resistive-type humidity measurement component, an NTC temperature measurement component and a high-performance 8-bit micro controller inside, and provides calibrated digital signal output. It has high reliability and excellent long-term stability, thanks to the exclusive digital signal acquisition technique and temperature & humidity sensing technology. -
