Elke meter heeft een aantal sensoren. Iedere sensor heeft een ID. In onderstaande tabel zijn de sensoren opgenomen.

Sensor Omschrijving ID
UVA Ultraviolet A is a long-wave, black light, not absorbed by the ozone layer: soft UV. 214
UVB Ultraviolet is electromagnetic radiation shorter than that of visible light but longer than X-rays. 215
UVC Ultraviolet is electromagnetic radiation shorter than that of visible light but longer than X-rays. 216
Battery level The SCK remaining battery level in percentage. 10
Digital Barometric Pressure Sensor Barometric pressure is the pressure within the atmosphere of Earth. 58
Digital Ambient Light Sensor Lux is a measure of how much light is spread over a given area. A full moon clear night is around 1 lux, inside an office building you usually have 400 lux and a bright day can be more than 20000 lux.", 14
SD Card Presence This value is 1 if there is a micro SD-card inserted in the kit, and will be 0 otherwise. 221
Particulate Matter PM1 M stands for particulate matter: a mixture of solid particles and liquid droplets found in the air. PM1 refers to particulate matter. 193
Particulate Matter PM10" PM stands for particulate matter: a mixture of solid particles and liquid droplets found in the air. PM10 refers to particulate matter. 196
Particulate Matter PM2.5 PM stands for particulate matter: a mixture of solid particles and liquid droplets found in the air. PM2.5 refers to particulate matter. 194
Particulate Matter PM4.0" PM stands for particulate matter: the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye/ 195
Particle Matter PN0.5 Particle Number Concentration from previous size to 0.5um. 197
Particle Matter PN1.0 Particle Number Concentration from previous size to 1.0um. 198
Particle Matter PN10.0 Particle Number Concentration from previous size to 10.0um. 201
Particle Matter PN2.5 Particle Number Concentration from previous size to 2.5um 199
Particle Matter PN4.0 Particle Number Concentration from previous size to 4.0um. 200
Particle Matter Typical Particle Size Typical Particle Size 202
Humidity elative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold. For instance, if the relative humidity was 50%, then the air is only half saturated with moisture. 56
Temperature Air temperature is a measure of how hot or cold the air is. It is the most commonly measured weather parameter. Air temperature is dependent on the amount and strength of the sunlight hitting the earth, and atmospheric conditions, such as cloud cover and humidity, which trap heat. 55
Noise Level Sound pressure level (SPL) or sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels (dB) above a standard reference level. 53
Wi-Fi antenna Received signal strength indication (RSSI) is a measurement of the power present in a received radio signal. 220

In onderstaande tabel staan de instructies waarmee de gegevens opgevraagd kunnen worden. Deze gegevens worden in een CSV (Comma gescheiden) bestand aangeleverd. De instructie regel moet je in het zoekveld van de browser ingegeven. Vervolgens wordt de data weergegeven. 

op te vragen data instructieregel toelichting
de laatste meetwaarden https://api.smartcitizen.me/v0/devices/ID Vul voor ID het ID van de meter in.
historische waarden https://api.smartcitizen.me/v0/devices/ID/readings?sensor_id=SENSOR_ID&rollup=10s&from=DATE&to=DATE Vul voor ID het ID van de meter in. Vul voor SENSOR_ID het sonsor ID in. Vul voor DATE de start en eind datum in. Format is 2025-02-01. Begindatum is van 00:00u van de ingevulde datum tot 00:00u van de ingevulde Einddatum. Er worden dus geen metingen van de Einddatum meegenomen.
