HC-SR04 Ultrasonic Module HC-SR04
The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. From 2cm to 400 cm or 1” to 13 feet. It operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect). It comes complete with ultrasonic transmitter and receiver module.

Product Description:
We are the leading suppliers for DHT 11 Temperature Humidity Sensor Module. DHT11 is a Humidity and Temperature Sensor, which generates calibrated digital output. DHT11 can be interface with any microcontroller like Arduino, Raspberry Pi, etc. and get instantaneous results. DHT11 is a low cost humidity and temperature sensor which provides high reliability and long term stability.
It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and outputs a digital signal on the data pin (no analog input pins needed). Its very simple to use, and libraries and sample codes are available for Arduino and Raspberry Pi.
This module makes is easy to connect the DHT11 sensor to an Arduino or microcontroller as includes the pull up resistor required to use the sensor. Only three connections are required to be made to use the sensor – Vcc, Gnd and Output.
It has high reliability and excellent long-term stability, thanks to the exclusive digital signal acquisition technique and temperature & humidity sensing technology

433Mhz RF Transmitter and Receiver
433Mhz RF Transmitter Receiver Module best price Pakistan are very cheap and you can use them with any microcontroller (MCU). Which is used in Remote control for cars , or to control simple tasks , like control relay on/off unfortunately I didn’t find What I need , So i decided to write a simple artical about this transceiver and How we can connect it with arduino and program it. These RF modules are very popular among the Arduino tinkerers. The 433MHz is used on a wide variety of applications that require wireless control. This is 433Mhz RF transmitter with receiver kit for Arduino ARM MCU wireless
