DS3231 Real Time Clock (RTC) Module, 32K (DS3231)
This Infrared Obstacle Avoidance Sensor Module is an inexpensive solution to avoidance detection for robotics and other electronics uses. It comes as an assembled module, as shown above, there are only four pins: 5-volts, GND, output, and EN. Output is an active LOW and has an onboard status LED. It’s very easy to interface directly with micro-controllers. It also works with the Raspberry Pi with a voltage range of 3-6 volts. Connect Vcc to 3-volts.
The enable pin “EN” will disable the device when HI (Vcc) and enable when LO (GND). The onboard jumper can be left open to allow external control of enable/disable of the module. There are two potentiometers on the module one controlling operating frequency (centred at 38 kHz) the other controlling intensity. The detector was designed for 38 kHz and the onboard oscillator circuit is based on a 555 timer.

Infrared IR Distance / Proximity Sensor Sharp GP2Y0A02YK0F (GP2Y0A02YK0F)
The Sharp distance sensors are a popular choice for many projects that require accurate distance measurements. This IR sensor is more economical than sonar rangefinders, yet it provides much better performance than other IR alternatives. Interfacing to most microcontrollers is straightforward: the single analog output can be connected to an analog-to-digital converter for taking distance measurements, or the output can be connected to a comparator for threshold detection. The detection range of this version is approximately 20 cm to 150 cm (8″ to 60″).
The GP2Y0A02 uses a 3-pin JST PH connector that works with our 3-pin JST PH cables for Sharp distance sensors (not included); the top picture on the right shows a shorter-range Sharp analog distance sensor with one of these cables. These cables have 3-pin JST connectors on one end and are available with pre-crimped male pins, pre-crimped female pins, and with unterminated wires on the other end.

White TEC1-12706 Thermoelectric Peltier Cooler Module, 12V (TEC1-12706)
hermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side is used. You can also use temperature differential to generate electricity.
A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying DC power source to a TEC, heat will be transferred from one side of the module to the other. It creates a cold and hot side. They are widely used in industrial areas, for example, computer CPU, CCDs, portable refrigerators, medical instruments, and so on.
When exposed to different temperatures on both sides it will also work as a generator and generate electricity depending on the temperature difference
