Most Andivi sensors are meant to fulfill the needs of buildings application areas. By far the most requested sensor is the Modbus Temperature Humidity Sensor which comes in several different variations and casings with different IP protection. In this blog post, we will take a look at all the variations of this sensor and introduce which finishes can be delivered to you.
Indoor and Outdoor casing – standard sensor application with or without LED display
All Modbus Temperature Humidity Sensors come with a measuring range:
- temperature: from -30°C to +70%C (equals from -22°F to +158°F),
- humidity: from 0% to 100% relative humidity.
The tolerance levels for this sensor are:
- temperature: +/- 0,5K tolerance
- humidity: +/- 2% tolerance for humidity.
The most common Modbus Temperature Humidity Sensor versions are in the:
- Wall-mounted sensor / Surface mounted – IP30 protected indoor housing (case) for mounting on the inside of buildings (rooms, halls, suspended ceilings, etc.),
- Universal application – IP65 protected outdoor housing (case) for mounting on different surfaces outside of buildings (outer walls, air ducts, roofs, ventilation ducts …).
Both – the IP30 and IP65 cases can be optionally delivered with a bright LED display indicating real-time measured values of temperature (°C) and humidity (%).
All Andivi sensors are manufactured in EU and come with a 3-year warranty – that is also extendable to 5 or 7 years.
Modbus temperature humidity sensor for indoor use – IP30 (example without and with LED display)
Modbus temperature humidity sensor for outdoor use – IP65 (example without and with optional LED display)

Additional possibilities sensor upgrades for Custom Electronics Hardware Development
There are several different Modbus RS485 sensors variatiobs that besides temperature and humidity can also measure:
- CO2 sensors (ppm),
- Air quality sensors (ppm),
- presence sensors (detected/not detected in past X minutes/seconds),
- occupancy sensors (amount of people in room/counting of people)
- brightness sensors (lux),
- noise sensors (dB),
- vibration sensors (m/s2),
- pressure sensors (bar).
- force sensors (N to kN),
- fluid property sensors,
If you are looking for a custom sensor or several sensors on a PCB that has to be tailored according to your specifications and designs, we can help you further in our agile R&D department. We have a small, but powerful agile hardware and software development team that can help you out with custom electronic development. We can support you with electronic hardware and software development – from the basic phase of creating a prototype to helping you get your batch mass-produced and all the milestones in between. We have a variety of reliable suppliers and we have created various hardware electronic products for leading building automation companies.
