Plant-powered sensors send signal to space
The extremely low power device sends signals at radio frequencies that are picked up by satellites in low Earth orbit. It was developed by Dutch company Plant-e and Lacuna Space, which is based in the Netherlands and the UK, under ESA’s programme of Advanced Research in Telecommunications Systems (ARTES).
The device can inform farmers about the conditions of their crops to help increase yield, and enable retailers to gain detailed information about potential harvests.
