精准农业是提高生产力和保护水资源的一个潜在的备选方案。特别是，可以通过使用土壤传感器收集土壤条件来优化灌溉活动，以确保水资源的可持续性。虽然有商业化的土壤监测系统，但其成本往往太高，无法大规模实施。为了通过灌溉优化来保证水资源的可持续性和粮食供应，需要大规模部署土壤传感器。因此，在这项研究中，开发了一种具有成本效益的土壤监测设备，采用电容式触摸传感和印刷电子产品。包括传感器探头和网关的拟议系统的目标价格为1000美元。这比商业上可用的系统便宜大约三倍，而且相当准确。在印度，灌溉优化对于缓解气候变化造成的严重干旱和水资源短缺至关重要。因此，为了验证所提出的探头在真实的农田中用于灌溉管理的可用性，在海得拉巴的玉米田中测试探头。所部署的探针成功地检测了由于降水和灌溉引起的土壤水分变化，这对于灌溉优化是有用的。
Precision agriculture is a potential candidate for enhancing productivity and conserving water resources. In particular, irrigation activities can be optimized by collecting soil conditions using soil sensors to ensure water resource sustainability. While there are commercialized soil-monitoring systems, their cost is often too high for large-scale implementation. To guarantee water resource sustainability and food supply through irrigation optimization, large-scale deployments of soil sensors are required. Therefore, in this study, a cost-efficient soil monitoring device that employs capacitive touch sensing and printed electronics was developed. The target price of the proposed system that includes a sensor probe and a gateway is $1000. This is about three times cheaper than the commercially available systems and it is reasonably accurate. In India, irrigation optimization is essential to mitigate severe drought and water shortage caused by climate changes. Thus, to verify the usability of the proposed probes for irrigation management in a real farm field, the probes were tested in a maize field in Hyderabad. The deployed probes successfully detected soil moisture changes due to precipitation and irrigation, which is useful for irrigation optimization.
