Hi Kristy,
We use HOBO, T&D and recently Wireless Sensor Tags. T&D has sensors that are either wireless or hooked up directly to ethernet. They are a bit pricier but reliable, send alerts, and can be viewed live from your account on their website. Graphs can also be viewed and downloaded from the site, and don't write over. Wireless Sensor Loggers are super small and affordable, and also take light readings. They are not great for long range but work fine in short range. The good thing about these is that the readings are saved on the Cloud so you can view an entire continuous reading for each Tag! I think T&D is better for long term monitoring and the Tags for short term projects. Both can be easily recalibrated onsite, which we try to do annually.
