This VOC Gas Sensor (SGP40) is an innovative environmental sensing module developed for a wide array of Volatile Organic Compound (VOC) detection applications.
This temperature & humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and the temperature is measured by a negative temperature coefficient (NTC) thermistor.
The Grove - Speaker is a module consist of power amplification and voice outputs. The loudness can be adjusted by the on-board potentiometer. With different input frequency, the loud-speaker generated different tones. Coding the music into arduino, DIY yo
Grove - Piezo Vibration Sensor is suitable for measurements of flexibility, vibration, impact and touch. The module is based on PZT film sensor LDT0-028.
Grove - OLED Yellow&Blue Display 0.96 is built 128x64 resolution with a blue and yellow bi-color display. It can be light up by either I2C or SPI interface.
