TM1637 4-Digit Display + IR Proximity Sensor

Package Includes:

• 1 x TM1637 4-Digit Display
• 1 x IR Proximity Sensor

Specifications

1. What is a 4-digit 7-segment display?

• This 7-segment LED Display has 4 digits which are controlled by the TM1637 Driver Chip. It requires only two connections to control this TM1637 4 Digits 7 Segment Led Display Module. Also thanks to the I2C bus you can control it using only 2 wires, leaving more pins available on your Microcontroller to connect other things.

2. How does a TM1637 4 Digit 7-Segment LED Display work?

• The TM1637  4-digit 7-segment displays require 12 connection pins. The TM1637 IC is mounted on the back of the display module, which reduces the total wire to 4. Two pins are required for the power connections and the other two pins are used to control the segments. The module is a 12-foot clock with four common anode tubes (0.36 inch) display modules for driver IC TM1637, only two signal lines can make the MCU control four 7-segment digital tubes.

3. What is IR proximity sensor used for?

• Proximity sensors detect objects and obstacles in front of them. The sensor continues to transmit infrared light, and when an object approaches, the sensor detects it by monitoring the reflected light from the object.

4. What is an IR Sensor and why is it not visible?

• An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800. While measuring the temperature of each color of the light (separated by a prism), he noticed that the temperature just beyond the red light was the highest. IR is invisible to the human eye, as its wavelength is longer than that of visible light. Anything that emits heat gives off infrared radiation

5. Is proximity and IR sensor same?

• IR, or infrared, detects the presence of an object by emitting an infrared light beam. It functions similarly to ultrasonic sensors, but instead of sonic waves, it transmits infrared radiation. Infrared proximity sensors are made up of an IR LED that emits light and a light detector that detects reflection.
