OCCUPANCY SENSOR WITH LIGHT AND TEMPERATURE SENSOR FOR MODBUS COMMUNICATION

Occupancy sensing for better comfort & energy efficiency

One of the biggest challenges, that we are encountering today is the balance between comfort, security and the efficiency of energy. When it comes to occupants’ comfort in an indoor area, both residential as well as non-residential markets, the building constructors are providing a best in class experience for the occupants with well-equipped building automation solutions.

Indeed, the occupancy sensors helps to control different types of appliances such as ventilation, air conditioning, alarms etc… according to the presence of the occupants inside the building. This provides many benefits such as low energy consumption, less carbon dioxide emissions, life-span extension of devices and decrease in electricity cost.

Easy connectivity and data transfer

The S-PRE/Day-Night/T sensor is equipped with a Modbus interface, which provides easy setup and integration into large process control and automation systems. Indeed, the sensors measurements can be read in real-time over RS485 local network via the Modbus RTU protocol with Master-slave approach. 

The S-PRE/Day-Night/T acts as a slave, and it allows for building network of up to 15 slaves. Moreover, the data of S-PRE/Day-Night/T is accessible via the Modbus register table.
 

Presence/Motion:

The pyroelectric detector with a 31 pairs of facets Fresnel lens, concentrates the infrared radiation emitted by human body and divides the detection field into 62 zones. It has a 4 meters of detection distance, 6 meters of diameter of detection on the floor and a 100°angle of detection.

Light:

The built-in light sensor detects the level of light intensity in the area, which helps to identify the light and darkness in order to optimise the occupancy sensing.

Temperature:

The built-in temperature sensor can be used for monitoring the temperature level in a zone.

S-CO2/T (Limited stock) - Sensors

CO2 and temperature sensor for Modbus communication

Nowadays, the buildings are nearly air-tight, entailing a risk of poor indoor air quality if there is a lack of ventilation. Indoor air quality can generally be assessed by measuring the concentration of carbon dioxide, known to be representative of indoor air conditions. Aereco introduces the new S-CO2/T Modbus, an effective CO2 sensor specially designed to accurately assess indoor CO2 concentrations, in order to help systems optimize indoor air quality.
