Measurement History of One Station Sensor: Values with Min, Max and Mean over a Time Window (openSenseMap)

opensensemap/sensor-measurements

Measurements of one sensor of an openSenseMap station for a time window, newest first: the platform's default is the last two days, or give a from and to time in UTC. Returns the total count in the window, the minimum, maximum and mean of all of them and the newest 200 readings (time, value, position), with the oldest and newest times. Use list-boxes then get-box to find the station and sensor ids. Data from openSenseMap (opensensemap.org). Served by Eden Engine; not an official openSenseMap product.
