Specifications: Outdoor components: 1) Transmission range: maximum 100 meters (this is the maximum distance, measured under the condition of no interference and no obstruction. If there is interference and obstruction, the signal will be weakened.) 2) Transmission frequency: 433MHz 3) Outdoor humidity range: +20% to +59% (Resolution: 1%, accuracy: +/-5% in the range of 0-45℃) 4) Outdoor temperature range:-40°C to 60°C (resolution: 0.1°C, accuracy: +/-1°C) (Remarks: Theoretically, the sensor can work at sub-zero temperature, but the battery will not work if it is cold outside in winter. Suggestion: lithium battery.) 5) Measuring frequency: once every 48 seconds 6) Waterproof rating of outdoor components: IPX3 Interior components: 1) Indoor temperature range: 0℃ to 50℃ (Resolution: 0.1℃, accuracy: +/-1℃) 2) Indoor humidity range: +1% to +99% (Resolution: 1%, accuracy: +/-5%) 3) Air pressure range: 300hPa – 1100hPa Resolution: 0.1hpa, accuracy: +/-1.5hpa) Packing list: Receiver (display)*1 Temperature and humidity sensor*1 Power plug (European standard)*1
