4397	2020-02-25	Lab	Tested	Lab	I tested this sensor in the lab and could not get it to work. I used the current-to-voltage board provided with the sensor connected to a CR1000. I also connected a multimeter in place of the current-to-voltage board to measure the current. Both setups showed no response even when dunking the sensor in about 1.5m pipe filled with water. I recommend disposal.
4389	2020-02-20	Mayberry 0	Removed	Lab none	Removed from MB and brought back to the lab b/c it hasn't been comparing well to the regular CSI water level sensor.
4095	2019-09-04	Lab none	Installed	Mayberry 0	This new sensor is in the water next to the northeast corner post of the scaffolding. It was in about 21cm of water and about 5 cm above the bottom. Test to see if a cheap sensor can do as well as the expensive ones.
