The maximum line of sight communication range is about 100m.
Move the sensor assembly closer to the receiver.
Install a fresh set of batteries in the remote sensor(s).
Make sure the remote sensors are not transmitting through solid

Radio Frequency (RF) Sensors cannot transmit through metal
barriers (example, aluminum siding) or multiple, thick walls.
