sensat's Introduction

Angular Programming Exercise

Some environmental sensors have been deployed on the field. There are various types of sensors (CO, Temperature, O3, SO2, Humidity, …). Sensors are housed in boxes, and a box contains one sensor of each kind. Boxes have been placed at various locations. The sensor data has been collected in a JSON file with the following schema:

{
  "id": "Box-A1-O3", // UUID for this sensor reading
  "box_id": "Box-A1", // UUID of the box
  "sensor_type": "O3", // type of the sensor
  "name": "Ozone", // type of data read by sensor
  "range_l": 0, // measuring range lower bound
  "range_u": 1000, // measuring range upper bound
  "longitude": -0.06507, // location of the box (lon)
  "latitude": 51.51885, // location of the box (lat)
  "reading": 817, // actual value being read
  "unit": "ppm", // measurement unit
  "reading_ts": "2019-09-10T00:00:00" // when the reading was taken
}

The file can be found in the data/ directory

Basic Task

Write an Angular application which

reads the records from the sensor_readings.json
displays them in a tabular component (nothing too ugly)
allows the user to sort data by time and sensor type

Extra Tasks (two maximum)

allow user to enter new sensor data.
allows the user to filter data by sensor type/name.
plot a graph of sensor readings over time.
allow user to see sensor location on a map(use any lib google maps, openStreetMaps, openLayers, etc).
aggregate the data from all readings for the same sensor type, and compute the median of all its values. e.g

Box	Sensor Type	Median	Unit
Box-A1-O3	O3	321	ppm
Box-A1-TEMP	TEMP

Submission

Please include with your submission:

An explanation of any design decisions you've made (e.g. choice of libs, why you left parts out?, how you could improve this further, etc).
A brief guide on how to run the project.
