Whadda Line Tracking Sensor TCRT5000 Module

Replacement for Velleman VMA326
The Line Tracking Sensor based on TCRT5000 from Vishay is an type of infrared reflectance sensor, and is commonly used in line following robots, it is mounted at the bottom of the robot chassis. The line tracking sensor works by detecting reflected light coming from its own infrared LED and by measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it.

Whadda Air Quality Sensor Module VMA342

Replacement for Velleman VMA342
Ever wondered how good the air quality is in your living room? Or do you need proof of why you fall asleep in a non-ventilated meeting room after 3 hours? Look no further! This air quality sensor combo board will give you the answers in no time!

This air quality combo board senses the atmospheric-quality by using the popular CCS811 and BME280 ICs. It provides a variety of environmental data including barometric pressure, humidity, temperature, TVOCs and equivalent CO2 (or eCO2) levels. Communication is possible through the I2C protocol.

The CCS811 is an exceedingly popular sensor, providing readings for equivalent CO2 (or eCO2) in parts per million (PPM) and total volatile organic compounds in the parts per billion (PPB). The CCS811 also has a feature that allows it to fine-tune its readings if it has access to the current humidity and temperature. Therefore, we added the BME280, which provides humidity, temperature, and barometric pressure. This allows the sensors to work together to give us more accurate readings than they'd be able to provide on their own.

Since the CCS811 heats up a bit, the PCB is precisely designed to not influence the readings of the BME280 sensor.
