DS18B20 Waterproof Temperature Sensor Digital Temperature Probe In Pakistan
These temperature sensors work great with any microcontroller using any single digital pin. We can also connect multiple ones to the same pin. Each one has a unique 64 bits ID burn. It is useable with 3 to 5 volts systems. There is one downside of this sensor is they use the Dallas 1-wire protocol, and which is somewhat complex. This protocol requires a bunch of code to parse out the communication. When you are using this temperature sensor with a microcontroller put a 4.7K resistor to the sensing pin.

This is the DS18B20 Water Proof Temperature Probe which is based on the DS18B20 sensor. It is very handy when you need to measure something far away, or in wet conditions. Because they are digital, you don’t get any signal degradation even over long distances. These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. When using with a microcontroller put a 4.7k resistor to the sensing pin, which is required as a pull-up from the DATA to VCC line.

Digital LDR Sensor Module In Pakistan
The Digital Light Dependent Resistor LDR Sensor Module is used to detect the presence of light / measuring the intensity of light. The output of the LDR module goes high in the presence of light and it becomes low in the absence of light. You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is the digital output, so you will know is the light present and decide what to do with it.LDR photoresistor sensor module comes with an M3 mounting hole for ease of attaching it to an object. Onboard, it provides an LDR, high sensitivity and commonly being used for light detection.

IR Infrared Obstacle Avoidance Sensor Module In Pakistan
The Obstacle Detector sensor module is perfectly adaptable to the environment light, IR Object Avoidance Sensor has a pair of infrared transmitting and receiving tubes; transmitting tube emits infrared in a certain frequency, when detecting direction meets with obstacles(reflecting surface), reflected infrared will be received by the receiving tube; after the comparator circuit processing, the green indicator will light up, at the same time signal output interface to output digital signal(1 low-level signal). Users can adjust the detection distance through the potentiometer knob, effective distance range 2~30cm and working voltage is 3.3V to 5V. The Obstacle Avoidance module LM393 can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, black and white line tracking, and so on many occasions.
