- Durian growers tracking fruit ripeness on the tree
- Worth noticing
- It samples four times per second for 20–45 seconds, after taking that day’s ambient-air baseline.
Field notes
Each reading starts with a once-daily ambient-air reference; the operator then samples the same fruit at the same time each day. The page lists MQ-136, MQ-135, and MQ-3 sensors, then notes TGS2602 as an addition in revision G; it also describes temperature and humidity readings. It says measurements can be stored locally if the mobile-hotspot connection drops, while a distance sensor remains under test.
