With the Onset HOBO MX1101 data logger you can measure and transmit temperature and relative humidity data wirelessly to mobile devices via Bluetooth Low Energy (BLE) technology. Ideal for tracking warehouse storage temperatures, keeping tabs on humidity levels in museums, investigating occupant comfort complaints, and many more building monitoring applications.

Air pollution from biomass fuels in Africa is a significant cause of mortality and morbidity both in adults and children. This paper by D G Fullerton, S Semple, F Kalambo, A Suseno, R Malamba, G Henderson, J G Ayres and S B Gordon describes the nature and quantity of smoke exposure from biomass fuel in Malawian homes.

Summary
Over 2 billion people rely on biomass fuel as their main source of domestic energy. Most of these people live in developing countries such as Malawi, where more than 90% of people cook using biomass fuel (fig 1). Indoor air pollution associated with biomass fuel use is increasingly recognised as a major health concern in the developing world, responsible for an estimated 36% of mortality from respiratory disease as well as contributing to non-respiratory pathology.1 2 3 4 5 Pneumonia is the leading cause of death in children <5 years of age and the risk of pneumonia in young children is increased by exposure to unprocessed solid fuels

For this research - carried out by Lomas KJ and Kane T from the School of Civil and Building Engineering, Loughborough University - Hobo Data loggers supplied and calibrated by Tempcon Instrumentation were used to examine internal summertime temperatures in the living and bedrooms of 282 homes in the UK city of Leicester.

This being a statistically representative sample of the city's housing stock. The monitoring period, whilst generally cool, included a short period of hot weather.

Abstract
Internal summertime temperatures measured in 268 homes in the UK city of Leicester are reported. The hourly data was collected from living rooms and bedrooms during the summer of 2009, which was generally cool but with a short hot spell. Some household interviews were conducted. The
