Yeah, great question. I would love to have Nitrates, Phosphorous, Dissolved Oxygen and Ph capabilities also. I suspect that there is a calibration problem for a in stream sensor for these parameters.

Shannon Hicks replied to the topic MS One-Wire Power in the forum Environmental Sensors 2 years, 2 months ago
Onewire sensors like the DS18b20 don’t like to have their bus power cycled on and off. Back when I last experimented with them (with a different sketch not related to ModularSensors), if you’ve got the sensor connected to the switched power supply, you had to do “DSsensors.begin();” each time the logger woke and powered up the switched power b…[Read more]

hi Everyone,
I am new to the EnviroDIY world. I work at a nature center and we just installed our first water monitor. At the moment all we have is temp, depth and conductivity, but we are really after a nitrate monitor. We share a border with a golf course that drains directly into our pond, so being able to link a flood of nitrates di…[Read more]

To connect 3 pin One-Wire temperature senor I had wanted to use the Grove D10-11 port.
Power to 3.3V_SW
Sensor to D10
Ground to GND

Scott Ensign replied to the topic Turbidity Sensor Information/Questions in the forum Environmental Sensors 2 years, 3 months ago
Given the popularity, complexity, and expense of turbidity sensors, the team here at the Stroud Center has compiled a snapshot of some commercially-available options that may help people decide on the best option. This table likely excludes other vendors and models; it is intended to summarize those sensors that we have recently used or…[Read more]
