IMG_3618.jpgCOllineIO Board







CollineIO board is a general purpose inputs/outputs control board. It is able to manage digital and analog inputs/outputs.

It can works as a master or as a slave.

Working as a master, users can develop their own software to read/write to any input/output. Cerro will supply a software example and the users using free IDE from Cypress PSOC Creator, will create their own application. User can connect a touch panel to govern the full system.

Working as a slave, an external CPU, using industrial standard MODBUS RTU protocol will ask to the board the status of the inputs or set the outputs. The external CPU can use RS-485 or RS-232 to communicate with it. Another possibility is to plug a RaspberryPi (or other format size compatible) in the internal connector. CollineIO firmware will manage all the input/outputs according to the commands received from the external CPU.

CollineIO is based on PSoC Programmable System-on-Chip, CY8C5868AXI-LP035, ARM Cortex- M3, 256 KB Flash, 62 GPIOs and analogue peripherals.

A free test software helps to evaluate the board and the command protocol. Please download it from the documents tab.

Full System to measure the IAQ (Indoor Air Quality).
Includes different sensors and data recording in the cloud for analysis on large periods of time.
Ideal for hospitals, health centres, laboratories, offices, schools, universities, hotels, homes, industries, workshops.


BlueAir is a device that measure the quality of indoor air in real time. The air we breathe indoors may not be ideal for our health or work performance and is of special interest to people with respiratory problems. It is estimated that people spend 90% of their entire lives indoors.

Both the WHO (World Health Organization) and the EU (European Union) recommend the control of contaminants that can usually be found in indoor rooms: CO, CO2, fine particles (PM10 and PM2.5) and VOC (Volatile Organic Components) such as benzene, formaldehyde, naphthalene among others.

In some European countries directives on air quality have already been published in public spaces such as schools and hospitals.

The measurement of air quality is the first step to take actions such as increasing the ventilation of the place or filtering the air.

Sensors: CO2, VOC, CO, PM (2.5, 10), temperature, humidity, ambient noise
