The HAPEx is a wireless PM2.5 real time data logger used to assess kitchen concentration or personal exposure to particulate matter. This sensors is adapted to monitor PM2.5 concentration in the kitchen of solid fuel users where the concentration on PM2.5 can reach very high value. While most sensor will saturate a 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 scaterring PM sensor, the HAPEx sensitivity depends on the aerosol type. To make absolute PM2.5  measurements (expressed in ug/m3), the HAPEx sensor should be collocoated 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

Price:  starting at US$ 40 for 3 months rental (include pre and post calibration)

The EXACT sensor is a wireless Stove Use Monitor that can be used to measure the usage of any type cookstove in the household. Temperature measurement are done using a contactless infra red technology making our sensor very versatile. For instance, open fires are easy to monitor with the EXACT unlike other sensors that rely on direct measurement method.

The small size and high temperature rating (full metal contruction) enable it to be deployed directly on portable cookstoves that are moved frequently. The EXACT is fully water proof and dust proof and can be deployed outdoors if needed. Long deployement of up to 4 continuous years are possible!

In addition to these features, the EXACT also feature a unique background temperature compensation algorithm that remove diurnual ambient temperature swings and leave only the measured temperature of the stove above ambient. This  greatly simplify the data analysis and allow an on the fly simple threshold algorithm to give accurate cooking event

The key features of the EXACT are:

- Works on any stove (Infra-Red technology)

- Automatic background temperature  compensation

- Weather proof

- 4 years battery life

- Automatic cooking event detection

The FUEL sensor was developped 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 actual fuel consumption in a real life setting. The FUEL sensor exist in a tensile version (optimized for firewood, charcoal or agricultural residue) and a compressive version (optimized for LPG).

Specification:

       - 50 kg capacity

       - 0.1g resolution
       - Wireless connectivity for easy launch in the field
       - Internal storage for one millions logs (3 months @ 8s log rate)
       - Easy re-calibration with reference weight
