The HAPEx is a wireless PM2.5 real time data logger used to assess kitchen concentration or personal exposure to particulate matter. This sensor is adapted to monitor PM2.5 concentration in the kitchen of solid fuel users where the concentration of PM2.5 can reach very high values. While most sensors will saturate at 500 ug/m3, the HAPEx can reach 60,000 ug/m3. On the other end, the HAPEx sensor has a lower sensitivity at low concentration, the limit of detection is around 10 ug/m3.

Another strength of the HAPEx sensor is its very long battery life. The internal battery of the HAPEx can provide enough energy for 5 years of continuous measurement. Its small size and integrated accelerometer makes it perfect for personal exposure measurement.

Like other light scattering PM sensors, the HAPEx sensitivity depends on the aerosol type. To make absolute PM2.5 measurements (expressed in ug/m3), the HAPEx sensor should be collocated with a gravimetric sampler (like our uPump). It can then provide calibrated real time PM2.5 measurement.

The key features of the HAPEx sensors are:

- Small and light weight (1.4"x2.6"x0.9"; 1.4oz / 3.5cm*6,5cm*2cm ; 40g)

- Accelerometer for compliance monitoring

- Wide measurement range (10 µg/m³ - 60 mg/m³)

- 5 years battery life

EXACT Pro is fully featured and our most versatile Stove Use monitor. It records minute by minute temperature data and processes it on the fly using our advanced algorithm. It can communicate with our dedicated launcher as well as with our android app.

With our EXACT Pro, you have full control on log rates and cooking detection parameters. You can tailor its operation to your need and get detailed insight into complex cooking energy systems thanks to its integration with our datalogging scales (FUEL) and our PM sensor (HAPEx).

Storage & Battery life

A key feature of the EXACT line of sensors is their extremely low power consumption. That allows for battery life of 5 years while maintaining a low profile. Storage capacity higher than 130k measurements enables long term missions (for instance a year of data can be stored with a resolution of 4 minutes).

Advanced Internal Algorithm

Building on years of experience analyzing temperature profiles, we have developed an internal cooking detection algorithm that processes the data on the fly as they are measured. A summary of cooking events, cooking days and cooking time is available at download without the need for further data processing.

Integration into our wider line of sensors

EXACT is part of a wider ecosystem of sensors dedicated to cookstove impact assessment. It integrates seamlessly with our air quality (HAPEx) and our fuel consumption (FUEL) sensors.

The Unified Launcher is the main interface to all our sensors. It will enable you to launch or download data for several different sensors per household in a matter of minutes.

The main features of the launcher are:

- Rechargeable battery with long run time

- Store data to micro SD card

- Touch screen for easy operation of the sensors

The FUEL sensor was developed in partnership with the Oregon State University.

It logs fuel consumption in real time. It is an easier and less obtrusive alternative to the KPT. With its long battery life and wireless connectivity it empowers anyone to measure a stove's actual fuel consumption in a real life setting. The FUEL sensor exists in a tensile version (optimized for firewood, charcoal or agricultural residue) and a compressive version (optimized for LPG).

Specification:

- 20 kg capacity (we also have 50kg and 100kg options for deployment in institutional kitchens)
- 0.1g resolution
- Wireless connectivity for easy launch in the field
- Internal storage for one million logs (3 months @ 8s log rate)
- Easy re-calibration with reference weight
