Inkbird solar floating pool thermometer IBS-P03R 2nd — wireless IP68 transmitter with indoor monitor

Inkbird's IBS-P03R 2nd is a solar-powered floating pool thermometer with a wireless transmitter and indoor temperature/humidity monitor for accurate, hands-free water monitoring.

Keep track of water conditions without constant checks: this Inkbird kit combines a solar-charged floating sensor and a compact indoor display that reports real-time pool temperature, humidity, comfort level and historical min/max water temps. Built to resist impacts and continuous immersion with an IP68 integrated housing, the floating transmitter sends readings wirelessly to an indoor receiver up to about 980 feet away. It ships with two AAA batteries for the indoor monitor and includes power-saving solar cells on the transmitter so routine battery swaps are rare.

How does the solar power and battery system work?

The floating transmitter harvests sunlight to maintain operation and extend runtime, while the indoor monitor runs on two included AAA batteries. On a full solar charge, the transmitter can keep working for long stretches, and the receiver's batteries are straightforward to replace.

• Solar-charged transmitter reduces need for frequent battery changes.
• Indoor monitor runs on two AAA batteries (included) for easy maintenance.
• Power-saving design offers long operational periods between service.

How accurate and reliable are the readings?

The IBS-P03R 2nd uses a high-precision sensor that reports water temperature accurate to about ±1°C (±1.8°F). A wireless link transmits data to the indoor display up to roughly 980 feet under normal conditions, and the transmitter’s anti-collision ring helps protect the sensor from impact noise and movement.

• Sensor accuracy around ±1°C (±1.8°F) for dependable temperature readings.
• Wireless range up to approximately 980 feet for flexible placement.
• Anti-collision ring and integrated IP68 housing reduce false readings from bumps or splashes.

What does the indoor monitor display and how do I use it?

The indoor unit displays indoor temperature, relative humidity, current water temperature, a comfort indicator for the water, and recorded minimum and maximum water temperatures. Switching between Celsius and Fahrenheit, pairing the sensor, and reading the stored data are simple, making the system usable for pools, hot tubs, ponds and baths.

• Shows indoor temp, humidity, current pool temp, and comfort level at a glance.
• Records min/max water temperatures for trend tracking.
• Simple pairing and °F/°C switching for quick setup and viewing.

How durable is the floating transmitter in pool conditions?

Engineered for continuous water exposure, the transmitter uses an IP68-rated integrated design that resists water ingress and is built to float. The anti-collision bumper softens impacts from pool toys or walls, and the sealed construction helps prevent seepage and corrosion over time.

• IP68 waterproof rating for long-term immersion and splashes.
• Integrated, sealed housing prevents water entry and corrosion.
• Protective anti-collision ring reduces damage from impacts and noise.

Who this is for: the Inkbird IBS-P03R 2nd suits pool and spa owners who want continuous, low-maintenance water monitoring without wiring or frequent battery chores. It's useful for homeowners, caretakers of small community pools, pond keepers and anyone who prefers a wireless indoor display to check pool conditions from inside the house. If you want solar assistance, long wireless range and an IP68-rated floater with an easy-to-read indoor monitor, this kit is a practical choice.
