PARTICLE SENSOR Honeywell has announced a particle sensor designed to help building owners and consumers monitor the air for potentially harmful particulate contaminants caused by dust, soot and smoke. The HPM series particle sensor is designed to work in heating, ventilation and air conditioning (HVAC) systems, and consumer products such air purifiers, to measure air quality in homes, buildings and public spaces. It uses laser technology to monitor for fine inhalable particles that are 2.5 µm in diameter or smaller. It can be used in a range of consumer products such as air purifiers, automotive air systems and mobile air quality detectors. The sensor outputs an electrical signal that can be fed into HVAC control systems in buildings and homes or into other air monitoring devices. This information can alert building operators that air purification systems should be activated or if outdoor air could be used to improve indoor air quality, or when an air filter needs to be changed or early maintenance should be performed on indoor air delivery systems. The laser-based sensor uses a light-scattering method to detect and count particles in the concentration range of 0–1000 µg/m3 in a given environment. The sensor then analyses the particulate size and concentration in real time to enable systems to provide alerts and allow operators to take remediation actions. With its heavy industrial-level electromagnetic compatibility, the sensor performs in harsh, challenging environments. Building operators benefit from the sensor’s long life of 20,000 h, which allows for stable operation and continuous use. Honeywell Ltd www.honeywell.com.au
