Abstract
A modular data acquisition system includes a stacked assembly of a rain gauge module mounted on a data recorder module, in turn mounted on a water level sensor module which in turn is mounted on an observation well casing. Each module has a housing that is sized and configured to engage and nest with the adjacent housing and the housings can be locked together to minimize vandalism. The rain gauge module and the water level sensor module, have sensors that are electrically connected to a data recorder in the data recorder module through connectors on the module housings that are positioned to connect and establish electrical contact when the module housings are nested together.
