The emitter is an IR LED and the detector is an IR photodiode. The IR phototdiode is sensitive to the IR light emitted by an IR LED. The photo-diode’s resistance and output voltage change in proportion to the IR light received. This is the underlying working principle of the IR sensor.

The TCRT5000 are reflective sensors which include an infrared emitter and phototransistor in a leaded package which blocks visible light. The package includes two mounting clips.TCRT5000 sensor works with the general infrared sensor, like a sense of a TCRT5000 has an infrared emission tube and an infrared receiver tube.TCRT5000 Reflective Infrared Optical Sensor

The TTP223 is a touch pad detector IC which offers 1 touch key. The touching
detection IC is designed for replacing traditional direct button key with diverse pad size.
Capacitive touch allows electronics to sense when your finger is within a few millimetres
of a surface to simulate a button “press” just like how the pushbutton works. Capacitive
sensing may be used in any place where low to no force human touch sensing is
desirable.TTP223B Digital Touch Sensor

Barometric Pressure sensor measures the absolute pressure of the air around it. This pressure varies with both the air and altitude. Depending upon the interpretation of the data, changes in the weather can be monitored, altitude can be measured, and any task can be done that requires the accurate pressure measurement.

The rain sensor module is an easy tool for rain detection. It can be used as a
switch when raindrop falls through the raining board and also for measuring rainfall
intensity. The module features, a rain board and the control board that is separate for
more convenience, power indicator LED and an adjustable sensitivity though a
potentiometer. The analog output is used in detection of drops in the amount of rainfall.
Connected to 5V power supply, the LED will turn on when induction board has no rain
drop, and DO output is high. When dropping a little amount water, DO output is low, the
switch indicator will turn on. Brush off the water droplets, and when restored to the initial
state, outputs high level.Raindrops Sensor Module MH-RD

There are two types of reed switches: “normally open” reed switches and “normally closed” reed switches. The metal reeds on a normally open switch stay open when there is no magnet near the switch. In the presence of a magnetic field, the contacts of a normally-open reed switch will close. A normally-closed reed switch is closed when it is not near a magnet; as a magnet is brought close to it, a normally-closed switch will open
