Soil Moisture Microsensor Gas Sensors MoO3 In-situ Agriculture Applications

Sandeep Surya, et al., " Molybdenum Trioxide (MoO3) Capacitive Soil Moisture Microsensor for In-situ Agriculture Applications: Measurement Studies and Temperature Effects". The soil moisture sensor is of utmost importance in agriculture due to issues including water conservation and disease prediction. This work presents the design and development of a molybdenum trioxide (MoO3) based capacitive soil moisture microsensor. The sensor comprises an inter-digitated electrode (IDE) on a silicon wafer and MoO3 is drop cast on IDE, which acts as the sensing film. IDE on Si wafer is mounted on the
