• This is D1 Mini V2 NodeMcu 4M Bytes Lua WIFI Internet Of Things Development Board Based ESP8266, it is a mini WIFI board based on ESP-8266EX.
• 11 digital input/output pins, all pins have interrupt/PWM/I2C/one-wire supported(except D0) 1 analog input(3.3V max input) and a Micro USB connection.
• The development board features WiFi-SoC ESP8266 and is made for fast Internet-of-Things (IoT) prototyping.

• MAX30100 Pulse Oximeter Heart Rate Sensor Module is an integrated pulse oximeter and heart-rate monitor sensor solution
• Its an optical sensor that derives its readings from emitting two wavelengths of light from two LEDs a red and an infrared one then measuring the absorbance of pulsing blood through a photodetector
• This particular LED colour combination is optimized for reading the data through the tip of ones finger
• The pulse oximetry subsystem in MAX30100 consists of ambient light cancellation (ALC), 16-bit sigma delta ADC, and proprietary discrete time filter.
• MAX30100 operates on a supply in the range of 1.8 to 3.3V.It can be used in wearable devices, fitness assistant devices, medical monitoring devices, etc.The MAX30100 operates from 1.8V and 3.3V power supplies and can be powered down through software with negligible standby current, permitting the power supply to remain connected at all times

• BME680 Digital Humidity Temperature Pressure High Altitude Sensor Module is a digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement based on proven sensing principles.
• The gas sensor on the BME680 can detect a wide variety of volatile organic compounds to monitor indoor air quality. The sensor has high-linearity and high-accuracy.
• The BME680 is specially developed for mobile applications and wearables where size and low power consumption are critical requirements.
• he BME680 has features like specific operating mode, optimized power consumption, long-term stability, and high EMC robustness. In order to measure air quality, the gas sensor within the BME680 can detect a broad range of gases such as volatile organic compounds (VOC). To learn more about the BME680 Sensor, you can check BME680 Datasheet.
