Telemetry has been used by weather balloons for transmitting meteorological data since Oil and gas industry[ edit ] Telemetry is used to transmit drilling mechanics and formation evaluation information uphole, in real time, as a well is drilled. These services are known as Measurement while drilling and Logging while drilling. Information acquired thousands of feet below ground, while drilling, is sent through the drilling hole to the surface sensors and the demodulation software.
The sensor can also be used to detect combustible gases, especially methane. This sensor has a high sensitivity and fast response time. The drive circuit is very simple. This circuit can detect leakages in your Home, car or in a service station, storage tank environment.
This unit can be easily implemented to industrial level by upgrading its ranges. Pin details of the gas sensor module are shown in Fig. An MQ-6 gas sensor is used in the gas sensor module.
As per its datasheet, it has high sensitivity to propane, butane, isobutene, LPG and natural gas. This circuit has been tested with LPG gas and was found to work very fine.
Whenever there is LPG con-centration of ppm parts per million in the area, the OUT pin of the sensor module goes high. This signal drives timer ICwhich is wired as an astable multivibrator.
The multivibrator basically works as a tone generator. LED1 glows and the alarm sounds to alert the user of gas leakage. The pitch of the tone can be changed by varying preset VR1.
Use a suitable heat-sink for transistor SLReceive sms gsm module using pic microcontroller, In this article you will learn how to receive sms using gsm and pic microcontroller. I have already posted many articles on gsm and gsm module interfacing with pic microcontoller.
City Garbage collection indicator using RF(Zigbee) project called City Garbage collection indicator using RF and GSM technology. In these dustbin are interfaced with microcontroller based system having IR wireless system.
These Dustbin are interfaced with the central System . In addition, it has a great feature of detecting accidents and informs specific people via SMS with location and speed of the bike before the accident occurs with the help of GPS GSM based tracking system, thus aiding ambulance to reach the correct rutadeltambor.com have implemented all the sensors within the helmet, which will send the information.
The main objective of this project is to devise a simple low cost microcontroller based weather monitoring system using wireless technology which fetches weather conditions using various sensors like temp, humidity etc, displays it on LCD and forwards it to remote user by rutadeltambor.com project is.
Microcontroller-Based Temperature Monitoring and Control is an essential and practical guide for all engineers involved in the use of microcontrollers in measurement and control systems. The book provides design principles and application case studies backed up with sufficient control theory and electronics to develop your own systems.
digital ohmmeter Circuit diagram using pic microcontroller Circuit diagram of digital ohmmeter using pic microcontroller is given below. As shown in figure below, resistance R1 is pulled with 5 volt source and resistance whose value we want to measure is connect with ground and other terminal of resistance R1.
