The LIDAR-Lite 3 Laser Sensor is an essential, powerful, scalable and economical laser based measurement solution supporting a wide variety of applications (eg, drones, general robotics, industrial sensing and more). Measures distance, velocity and signal strength of cooperative and non-cooperative targets at distances from zero to more than 40 meters.
The HC-SR501 Pyroelectric Infrared Sensor is used to detect the presence of people. It is commonly used in turning the lights on and off automatically when people arrive or leave. It is very reliable for robot projects which need human detection.
Adafruit BME680 - Temperature, Humidity, Pressure and Gas Sensor
This sensor can accurately detect temperature and humidity, it is easy to use thanks to the I2C interface, has low power consumption and resolution can be set to 8 or 12 bit for temperature and 12/14 bits for humidity.
This product is a module with 8 analogue infrared sensors useful for building your own line follower. Infrared sensors are based on the radiation property of this wavelength, ie the white areas reflect the received IR radiation, and the black surfaces absorb the received IR radiation.
If you've ever ordered and wire up a 9-DOF sensor, chances are you've also realized the challenge of turning the sensor data from an accelerometer, gyroscope, and magnetometer into actual "3D space orientation"!
This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power-savings options. Each sensor provides a separate digital I/O-measurable output.
The SparkFun CCS811/BME280 Environmental Combo Breakout takes care of all your atmospheric-quality sensing needs with the popular CCS811 and BME280 ICs.
MQ-3 is a highly sensitive gas sensor to alcohol concentrations in the atmosphere. It has low cost and long life with a simple drive circuit and is very useful for detectors used in breath analyzer, environmental monitoring, and in safety devices inside vehicles.
MPU9250 and BMP280 10DOF has 4 sensors which provide very useful functions for your projects and can be used in wide range of applications. This module integrates Accelerometer, Gyroscope, Magnetometer and Digital Barometer in one tiny module.
