Smoke Sensor/MQ-2

The MQ-2 smoke or (Gas sensor) is sensitive to smoke and to the following flammable gases: LPG, butane, propane, methane, alcohol and hydrogen. The resistance across the sensor is different depending on the type of the gas. The smoke sensor has a built-in potentiometer that allows you

RTC-Real Time Clock-DS1307

The DS1307 Serial Real-Time Clock is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially via a 2-wire, bi-directional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month

Temperature Sensor-DS18B20

The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor.In

Moisture Sensor-REES52

The soil moisture sensor or the hygrometer is usually used to detect the humidity of the soil. So, it is perfect to build an automatic watering system or to monitor the soil moisture of your plants. The sensor is set up by two pieces: the electronic board

Rain Sensor-FC-37 or YL-83

The rain sensor module is an easy tool for rain detection. It can be used as a switch when raindrop falls through the raining board and also for measuring rainfall intensity. The module features, a rain board and the control board that is separate for more convenience,

BMP180-Pressure Sensor

BMP180 is a good (Barometric Sensor) pressure sensor of BMP XXX series. This types designed to measure Barometric Pressure or Atmospheric pressure. BMP180 is a high precision sensor designed for consumer applications. Barometric Pressure is nothing but weight of air applied on everything. The air has weight

DHT11/DHT22 Temperature and humidity Sensor

The DHTxx series is a commonly used Temperature and humidity sensor. The sensor comes with a dedicated NTC to measure temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial data. The sensor is also factory calibrated and hence easy to interface

ESP8266 Web Server with Arduino

ESP8266 is WiFi module that act as Transceiver. ESP8266 is a UART TO wifi module which provides an easy way to connect any microcontroller platform like arduino to Internet wirelessly. ESp8266 is cheap and easy to work with it become one of the leading platforn for the
