Greenhouse (GHS) system is a system, that provides an efficient condition to grow plants. This research paper describes designing of a greenhouse system to control climate, soil moisture, lighting using fuzzy logic. The proposed model consists fuzzy logic to control GHS parameter such as temperature, Humidity, light, soil moisture and watering system to the plant. In this proposed system temperature controlling controller is used to take current temperature as input by using temperature sensor and its deviation from user set data. The temperature is controlled by the speed of fan. This algorithm is same for all other parameters. In this research the set value of different sensors is selected by the owner of the greenhouse according to the basis of growing plant condition. This system will enhance the capability of fuzzy logic control systems in case of process automation and potentiality.Simulation using MATLAB is used to achieve the designed goal.

Background: Solid fuel use was found to be associated with under-five mortality in low- and lower-middle income countries (LMICs). However, the current understanding of this association for Bangladesh is absent through around 80% of the total households in Bangladesh used solid fuel and the higher under-five mortality rate is a significant public health burden. We explored the associations of household cooking fuels used and the level of exposure to HAP through cooking fuels used with neonatal, infant, and under-five child mortality in Bangladesh. Methods: We analysed 4,198 mother-child dyads data extracted from the 2017/18 Bangladesh Demographic and Health Survey data. Type of cooking fuels used (solid fuel, clean fuel) and level of exposure to HAP through cooking fuels used (unexposed, moderately exposed, highly exposed) were considered as exposure variables. Neonatal, infant and under-five mortality were considered as the outcome variables. Relationships between the exposure and outcome variable were explored by using the multilevel mixed-effect logistic regression model adjusting for possible confounders. Results Solid fuels were found to be used in nearly 80% of the total mothers analysed. A higher likelihood of mortality was found among neonates (aOR, 3.78; 95% CI, 1.14- 12.51) and infants (aOR, 2.93; 95% CI, 1.60-6.15) of the women who used solid fuels as compared to the mothers who used clean fuel. The association was found strongest when we considered solid fuel used together with place of cooking. The likelihood of neonatal and infant mortality was found 4.33 (95% CI, 1.16-16.23) and 2.05 (95% CI, 1.18-7.23) times higher among mothers who were highly exposed to solid fuel used as compared to the mothers who were unexposed to solid fuel used. Conclusion Solid fuel used and its increased exposure increased the occurrence of neonatal and infant mortality. Prioritizing the use of clean fuel use and increasing awareness about the adverse effects of solid fuel use are important.

Intelligent home automation has become more popular over the decade. Integration of automation in a home security, enhances its self-dependability. An intelligent home, integrated with various smart system modules can provide convenient and safe environment for the inhabitants and home appliances which can be easily controlled and monitored even from a remote distance. In this paper an intelligent home automation and environmental solution is proposed along with the architecture of integrated sensor modules. This proposed system is embedded with electronic lock driven with password verification and biometric finger print scanner. This sensing tools ensure the system to prevent unauthorized access. It is comprised with video recording of unauthorized person or intruder moving around the home or office premises. Moreover, PIR motion sensor, IR sensors would also work as safeguard by helping to capture image and Skype video calling from the inside of home or office. User will also be able to monitor the present condition of the home or office by using Facebook post of image and message status. The implemented system as a prototype for the justification and attestation of the proposals has been tested successfully. The observed data ensures that the system is working efficiently.
