5mm 5537 LDR is a 5mm light-dependent resistor with a « 5537 » model number, which is a photosensitive component that changes its electrical resistance based on the intensity of ambient light. Its resistance is high in darkness and decreases as light increases, making it useful for light-sensitive applications like automatic lighting systems, alarms, and light-level detection.
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
The SHT3x sensor is the most accurate and precise sensor for measuring humidity and temperature parameters compared to other temperature sensors like LM35, Thermistor, DS18B20 & DHT11/DHT22. Thus SHT3x can be used for industrial applications because of the high accuracy and good sensitivity. Its Relative Humidity operating range is 0 – 100% and Temperature operating range is -40° to +125°C (-40° to +257°F).
The MQ3 analog gas sensor is suitable for detecting alcohol; this sensor can be used in a breathalyzer.
It has high sensitivity to alcohol and low sensitivity to gasoline.
The sensitivity can be adjusted using a potentiometer.
The HW-201 IR infrared obstacle detection module can detect obstacles within a distance range of 2 cm to 30 cm, with a detection angle of 35 degrees.
It can operate with a supply voltage of 3.3 V to 5 V and has a maximum current consumption of 100 mA. The module outputs a digital signal, high when an obstacle is detected, low when no obstacle is detected.
The infrared LED has a wavelength of 940 nm and an operating frequency of 38 kHz. The module operates at temperatures between -25 °C and +55 °C.
