Announcement of Price Adjustment

Dear Customers/Partners,

Thanks very much for your support to our company. Please kindly be noted that as the micro controller cost keeps increasing, sensor price will be adjusted from Nov 1, 2021. All proforma invoices or quotation will be expired if payments does not arrive before Nov 1. The new invoices/quotation will be updated according to the latest price list.

As the key IC’s lead time is longer than expected, the purchase orders will be reviewed specially based on the stock before acceptance. We are planning to switch to the backup suppliers as soon as possible, we still need some time to complete the smooth switch.

Please arrange your purchase plan in advance.

Best Regards,

CEO: Justin Wang
