Frequently asked questions
What is the battery life of OBSESSIO X1?
More than 2 years with one measurement per hour on a 3.6 V type A battery, according to its datasheet. A higher acquisition rate shortens the battery life; 4.8 to 32 VDC external power is possible. The project configuration must be specified to assess your needs.
Can the sensors be configured locally?
Yes. OBSESSIO X1, OBSESSIO X2 and DISTANCIO are configured and read locally from a smartphone, tablet or PC over Bluetooth/NFC; HORIZIO is configured over Bluetooth.
Which transmission options are available?
Depending on the model: Sigfox, LoRaWAN and LoRa P2P. The PACK FISSURE AUTONOME works with Sigfox or LoRaWAN. The datasheets of OBSESSIO X1, X2, HORIZIO and DISTANCIO also mention M2M radio protocols (Long Distance, Low Power). Tell us the connectivity constraints of your site.
