Abstract: A system (1) for measuring temperature and moisture of air and soil (3) with wireless data transmission, comprising at least one body (2) which is made of a biodegradable cellulose-based material. The body (2) has an underground part (8) and an above-ground part (9), at least one capacitive soil moisture sensor (4) of the soil (3), at least one resistance soil temperature sensor (5) and conductive paths (10) leading to the capacitive soil moisture sensor (4) and the resistance soil temperature sensor (5) are printed on the surface of the underground part (8) by printing technology. At least one bus (11) for data transmission is printed by means of printing technique on the surface of the above-ground part (9), to which the control unit (6), the radio communication module (7) with the antenna (12) and at least one digital air temperature and relative humidity sensor (13) are removably connected.
