Over the summer our research associate, Nanda Khaorapapong designed and built custom-made environmental sensing units, which we deployed into the gardens of 8 Seed Guardians. These units take readings from sensors measuring the temperature and moisture of the soil and air, the light, and the air pressure. They then send this data over a 3G network.
