PROBLEM TO BE SOLVED: To provide a bearing unit for a wheel with sensors capable of carrying out, at low cost, collection of information with respect to bearing load and conditions of use, and to collect information regarding the situation of road surface and use of vehicles in the market.SOLUTION: The bearing unit for a wheel with sensors has: a static wheel; a rotary wheel that rotates together with a vehicle wheel with the rotary wheel supporting the vehicle wheel; a plurality of rollers provided in a freely rolling manner between a static wheel side track formed on the peripheral surface of the static wheel and rotary wheel side track formed on the peripheral surface of the rotary wheel; and sensors. The sensors are capable of operating without receiving energy from the outside, and have functions of displaying a situation detected while retaining it, with at least one out of three sensors, namely, an impact sensor, moisture detection sensor, and temperature sensor, being installed within the inside of the bearing unit.
