The DT90 Series has been designed with an emphasis on low power, small size, and ease of deployment. This data logger is ideal for your remote monitoring environmental and industrial applications. There are two models available–the DT90L and DT90N. The DT90N is perfect for setting up small stations that require multiparameter sensors that only have a digital output. The DT90L is designed for multiparameter applications and can interface with both analog and digital sensors. Both options in this series share the same kernel board and core functionality.
