The HC-SR505 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.
The MQ-3 is a highly sensitive gas sensor to the alcohol concentrations in the atmosphere. It has a 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.
Adafruit BME680 - Temperature, Humidity, Pressure and Gas Sensor
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.
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 sensor detects several air quality elements with an accuracy of 15%. Easy to use multimeter to the I2C interface.
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. See description for more details about the product. Add to...

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"!
MS1100 Gas Concentration Senzor for Formaldehydes and Benzens
Matrix of Four Infrared Sensors for Robot Tracked Line
This sensor with 0.5m cable is for precision temperature sensing which can be used in laboratory, industrial processes, and more.
This set contains two sensors that are placed in opposite regions to create a monitoring area. If someone goes into this preset area, the sensors will detect this and send a signal to the central system they are part of.
This soil moisture sensor is used to read the amount of moisture present in the soil around the probe. It is ideal for monitoring soil moisture in your urban garden and detecting the moisture content of your soil for your indoor flower pots.
This small digital distance sensor detects objects between 2 cm and 10 cm (0.8″ and 4″) away. With its quick response time, small size, and low current draw, this sensor is a good choice for non-contact object detection, and our compact carrier PCB makes it easy to integrate into your project. See description for more details about the product. Add to...
