SenseCAP Wireless Barometric Pressure Sensor- LoRaWAN AS923 MHz
SenseCAP Wireless Barometric Pressure Sensor- LoRaWAN AS923 MHz is an IoT Sensor.
Product Overview
SenseCAP Wireless Barometric Pressure Sensor measures atmospheric pressure in the range of 300~1100 hPa. Featuring high-precision, stability, and high EMC robustness, this sensor is suitable for industrial applications such as weather stations, outdoor farms, tea plantations, greenhouses, and more.
This device incorporates a built-in LoRa transmitter based on SX1276 for long-range transmission, a barometric sensor, and a custom battery. It is specifically designed and optimized for use cases powering end devices by batteries for years. To minimize the power consumption, the device wakes up, transmits the collected air pressure data to the gateway, and then goes back to sleep.
Under the best of circumstances, the battery is expected to last for more than 8 years, depending on the environmental factors and data transmission intervals. Please kindly note that the default interval is once per hour. If you’d like to change the data upload interval, please refer to this document.

Policies & Guidelines
Warranty, shipping, and purchasing information
- All prices are stated in US dollars (USD), unless otherwise indicated.
- Full payment must be received and confirmed before an order is prepared or dispatched.
- Payment may be made by bank transfer, Bitcoin, or USDT. The payment methods available for each order are displayed at checkout.
- Shipping charges are shown separately at checkout. The quoted shipping charge includes applicable import duties, taxes, and customs-clearance charges for the delivery destination.
- An electronic invoice is made available in the Customer’s account after payment confirmation. An official sales invoice also accompanies the shipment.
- Orders may be cancelled for a full refund before order preparation begins. Once preparation has begun, cancellation is subject to the order’s processing status.
- A Customer wishing to return a non-defective product must request the return within 30 days of delivery. The product must be returned in good condition with its official sales invoice.
- For a non-defective return, the Customer is responsible for return shipping. The refund covers the product price only; the original shipping charge is not refundable.
- Refunds for returned products are initiated after the returned goods have been received and their condition verified. Approved refunds are initiated within seven business days and returned through the original payment method.
- The refundable amount is based on the USD value paid for the product. Refunds for Bitcoin or USDT payments are calculated against that USD amount, rather than a fixed quantity of cryptocurrency. The time required for funds to reach the Customer depends on the payment method and processing provider.
- All devices, sensors, and accessories purchased directly from SenseCAP are covered by a one-year warranty from the date of delivery.
- Warranty eligibility is verified against the original sales record and, where available, the product serial number. For products without a serial number, the order details and official sales invoice are used to identify the purchase.
- The warranty covers manufacturing defects and internal hardware failures arising under normal use and within the product’s specified operating conditions.
- Products that arrive damaged or non-operational should be reported to SenseCAP so that the appropriate shipping or warranty procedure can be arranged.
- Warranty claims are assessed through technical review. Depending on the findings, the resolution may include remote assistance, replacement parts, repair, or an equivalent replacement.
