Gorillacell Module 046: RGB Color Sensor

RGB Color Sensor is an input device used to measure the intensity of light across the three primary colors — red, green, and blue. The Gorillacell ESP32 Development Kit comes with an RGB Color Sensor module driven by the TCS34725 chip. It operates by illuminating an object with white light, then analyzing the reflected light through three color filters (red, green, and blue). Each filtered color is detected by dedicated photodiodes, allowing accurate measurement of color intensity and identification of the object’s color.

Gorillacell Module 045: RTC

Real Time Clock (RTC) stands for Real Time Clock, which provides accurate timekeeping over long periods because it has its own independent power source, typically a coin cell battery. This allows the clock to maintain the correct time even when the main system power is off. The Gorillacell ESP32 Development Kit comes with one RTC module driven by the DS3231 chip. The DS3231 is a high-accuracy I²C real-time clock that provides both date (year, month, and day) and time (hour, minute, and second) information.

Gorillacell Module 044: Fine Dust Sensor

The Fine Dust Sensor is an input device used to measure the air quality of the surrounding environment by detecting the concentration of dust and smoke particles in the air. The Gorillacell ESP32 Development Kit includes one Fine Dust Sensor module driven by the Sharp GP2Y10 sensor. It operates based on an optical detection principle, using an infrared (IR) LED and a photodiode arranged to measure the amount of light reflected by airborne particles. The intensity of the reflected light corresponds to the dust concentration in the air.

Gorillacell Module 043: Sound Sensor

The Sound Sensor is a device that detects sound waves and converts them into electrical signals. A common example of a sound sensor is the microphone, which acts as a transducer—converting sound vibrations in the air into analog electrical signals that can be processed by a microcontroller. The Gorillacell ESP32 Development Kit includes one Sound Sensor module for experimenting with sound detection, audio-based triggering, and noise level monitoring applications.

Gorillacell Module 042: Non-Contact Temperature Sensor

The MLX90614 is an infrared thermometer designed for non-contact temperature measurement. It can accurately measure the temperature of an object or person without requiring physical contact, making it ideal for applications such as thermal scanning, object temperature monitoring, and contactless safety systems. The Gorillacell ESP32 Development Kit includes one Non-Contact Temperature Sensor module driven by the MLX90614 chip for experimenting with infrared-based temperature detection projects.
