Abstract

Background/Objectives: Occurrence of natural disasters is unpredictable and needs very high attention. This paper mainly focuses on fire accident detection in Industries and houses and to reduce their severities. Methods/Statistical Analysis: This method has been implemented to detect fire accidents in industries which occur due to increase in temperature, decrease in humidity, release of hazardous gas like methane, butane, propane etc.; we have used DHT 11 sensor to detect temperature and humidity. MQ-2 sensor is to detect gas leakage. GSM module is used as a mode of communication for this method. Findings: We found that the statistical data available from these sensors can be used as a safety parameter and we can set the alert values depending upon the existing readings which we have obtained from the sensors used in the application. Previously we have observed that DHT11 sensor is interfaced to PIC16F877 Microcontroller. Temperature and humidity is monitored by LCD. We have introduced GSM module for Communication purpose. Whenever the Pre-set values are exceeded GSM module is activated through AT Commands sends the alert messages to mobile phones which we have already pre-loaded in the program. So that it can detect the fire accident occurred at particular location where we place the sensors. For this, we use ARDUINO UNOR3 development board which consists of ATMEGA 328 P-PU a 16 Bit Microcontroller programmed using ARDUINO IDE. All the sensors are interfaced to ARDUINO board and testing and verification is done several times to observe the accurate readings from the sensors. Applications/Improvements: By using this method, temperature and humidity measurements are monitored and the problem can be detected very easily. So we can take necessary precautions to reduce the fire accident.

Abstract

Batch sorption experiments were carried out using a novel adsorbent, Acid treated Pongamia Leaf Powder (APLP) and Acid treated Neem Leaf Powder (ANLP), for the removal of Chromium(VI) from aqueous solutions. Potential of APLP and ANLP for adsorption of chromium from aqueous solution was found to be excellent. Effects of process parameters pH, contact time and adsorbent capacity were studied. Langmuir model represent the experimental data well. Maximum dye uptake was found indicating that APLP and ANLP can be used as an excellent low-cost adsorbent. Comparison of adsorption capacity of APLP and ANLP for chromium clearly indicates that the capacity of APLP for adsorption of chromium is quite high than ANLP. It can be expected that APLP and ANLP would have similar capacities for dyes with similar molecular weight, structure and/or ionic load. Thus, the naturally defoliated the Pongamia and Neem leaf powders a low-cost natural resource, can be effectively used to remove pollutants from effluents.
