A globally active customer with a Chinese development office contacted the local Senseair sales office in China with a request for a carbon dioxide sensor. It was found that the Senseair standard sensors did not fully comply with their power constraints.
The solution was to increase the time interval between the measurement cycles from 2 seconds to 10 seconds. This should reduce the power consumption almost 5 times.
The project management communicated with the customer mainly through e-mail and phone conference since we were spread out in three countries on two continents. The sensor expert team at Senseair identified that the change also affected the automatic drift compensation algorithm and the calibration behavior since the IR light source operate in a different mode. A firmware engineer implemented the changes of the sensor microcontroller program. The calibration procedure was adjusted and tests were performed in order to guarantee full performance within the specified operating conditions.
At the end of the project, representatives from the European office performed a quality audit at Senseair in Sweden in order to qualify us as a supplier. The time from the contact with our Chinese office to start of production was 12 months. Since the goal of this development was in perfect agreement with the strategic plan, it was fully financed by Senseair.
